-Brief_I/O

   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
   op         I   The operation:  "GET" or "SET".
   lenout     I   Length of list for output.
   list      I/O  Specification of error messages to be output.

-Detailed_Input

   op      indicates the operation to be performed.  Possible
           values are "GET" and "SET".

           "SET" means, "the following list specifies the default
           selection of error messages to be output."  These are
           the messages that will be output to the default error
           output device (selected by errdev_c) when an error is
           detected.

           "GET" means, "return the current list of error output
           items."  This is the exact list that was set by the
           last call to this routine with the "SET" option.

           The option can be specified in mixed case.  For example,
           the following call will work:

           errprt_c ( "SeT", lenout, "ALL" )


   lenout  is the allowed length of list when list is returning a
           the error message list.  The size described by lenout
           should be large enough to hold any possible output plus 1.


   list    is a list of error message items.  The items
           are delimited by commas.  The items that can be
           in the list are the words:

           1.  SHORT        ...indicates the short error message
           2.  EXPLAIN      ...the explanation of the short message
           3.  LONG         ...the long error message
           4.  TRACEBACK    ...the traceback
           5.  ALL          ...indicates "output all messages"
           6.  NONE         ...indicates "don't output any messages"
           7.  DEFAULT      ...same as ALL, but includes default
                                message

           A "list" is a character string containing some or
           all of the above words, delimited by commas.  Examples
           are:

           1.  "SHORT, EXPLAIN"
           2.  "SHORT, LONG"
           3.  "ALL"
           4.  "NONE"
           5.  "ALL, NONE, ALL, SHORT, NONE"

           Each word in the list can be thought of as
           "flipping a switch" to enable or disable the output
           of the message(s) indicated by the word.  The
           words are acted on in the order they occur in the
           list, starting with the leftmost word.  As examples,
           consider the sample lists above.

           The effect of the first list above, "SHORT, EXPLAIN",
           is to enable the output of the short error message
           and the explanatory text corresponding to it.

           The effect of the second list is to enable the output
           of the short and long messages.

           The effect of the third list is to enable the output of
           all of the error messages (short, long, explanation
           of the short message, and traceback).

           The effect of the fourth list is to disable output of
           all of the messages.

           The effect of the fifth list is to disable output of
           all of the messages.  The reason for this is that
           the words in the list are responded to in order,
           from left to right, and "NONE" is the last word.

           If any words other than SHORT, LONG, EXPLAIN, ALL,
           DEFAULT, TRACEBACK or NONE appear in list, those words
           that are recognized are responded to.  The words
           that are not recognized are diagnosed as
           erroneous, and error messages are generated
           for each such unrecognized word.

           The length of list is caller-defined, but only
           the first 100 characters of list will be saved
           for later retrieval.

           Only the first 10 items in the list are used;
           the rest are ignored.

-Detailed_Output

   list    is a list of error message items.  The value of
           list is that set by the last call to this routine
           using the "SET" option.  See "Detailed Input"
           for a description of the possible values and
           meanings of list.

           The initial value returned is "DEFAULT".

           Only the first 100 characters of list are saved
           when the list is set; any additional characters
           are truncated.  Therefore, the first 100
           characters, at most, of the saved value of list
           will be returned.

-Parameters

   None.

-Exceptions

   1) If the input argument op does not indicate a valid operation,
      the error SPICE(INVALIDOPERATION) will be signaled.
      
   2) If the input argument list does not indicate a valid list of
      error message types, the error SPICE(INVALIDLISTITEM) will be
      signaled.
      
   3) The error SPICE(EMPTYSTRING) is signalled if the input
      string does not contain at least one character, since the
      input string cannot be converted to a Fortran-style string
      in this case.
      
   4) The error SPICE(NULLPOINTER) is signalled if the input string
      pointer is null.
 
   5) The user must pass a value indicating the length of the output
      string, when list is an output.  If this value is not at least 2, 
      the error SPICE(STRINGTOOSHORT) is signaled.

   Also, this routine is part of the CSPICE error
   handling mechanism.

-Files

   None.

-Particulars

   Please read the "required reading"!

   This routine is intended to be used in conjunction with
   errdev_c, which selects the default output device to which
   the error messages selected by this routine will be
   output.

   Additionally, the error response action must be
   something other than "IGNORE" if the error messages
   are to be output.  Possible choices of the error
   response action are "RETURN", "REPORT", "ABORT", "DEFAULT", and
   "IGNORE".  Use erract_c to set the error response action.


   Only the first 100 characters of list are saved.

   The default set of error messages that are output is the
   set specified by "DEFAULT"; i.e., all of them, including
   the "default" message.


-Examples

   1.  In this example, we select as the output device
       the file, SPUD.DAT, and then select the error
       messages to be output.  We choose the short
       error message and the traceback.  Since a
       different set of messages may have been selected
       previously, we clear the old setting by putting
       the word, "NONE", at the beginning of the list.

          /.
          Set the error output device to SPUD.DAT:
          ./
          errdev_c (  "SET", lenout, "SPUD.DAT" );

          /.
          Choose error messages:
          ./
          errprt_c (  "SET", lenout, "NONE, SHORT, TRACEBACK" );


   2.  In this example we are retrieving the error message list.

          /.
          Declare the output string and its size.
          ./

         #define     LENOUT  50

         SpiceChar   list[ LENOUT ];

         errdev_c ( "GET", LENOUT, list );


-Restrictions

   The device to which the selected error messages will
   be written must be selected via errdev_c; otherwise,
   messages will be written to the initial default device.

   Only the first 100 characters of list are saved.

-Detailed_Input
 
   handle         the handle of an EK file that is open for writing. 
                  A "begin segment for fast write" operation must 
                  have already been performed for the designated 
                  segment. 
 
   segno          is the number of the segment to which data is to be
                  added. Segments are numbered from 0 to nseg-1, where
                  nseg is the count of segments in the file.

   column         is the name of the column to be added.  All of 
                  the data for the named column will be added in 
                  one shot. 
 
   vallen         is the length of the strings in the cvals array.
                  The array should be declared with dimensions
                  
                     [nrows][vallen]
                     
                  where nrows is the number of rows in the column.
   
   cvals          is an array containing the entire set of column 
                  entries for the specified column.  The entries 
                  are listed in row-order:  the column entry for the 
                  first row of the segment is first, followed by the 
                  column entry for the second row, and so on.  The 
                  number of column entries must match the declared 
                  number of rows in the segment.  For columns having 
                  fixed-size entries, a null entry must be allocated 
                  the same amount of space occupied by a non-null 
                  entry in the array cvals.  For columns having 
                  variable-size entries, null entries do not require 
                  any space in the cvals* array, but in any case must 
                  have their allocated space described correctly by 
                  the corresponding element of the entszs array 
                  (described below). 
 
   entszs         is an array containing sizes of column entries. 
                  The Ith element of entszs gives the size of the 
                  Ith column entry.  entszs is used only for columns 
                  having variable-size entries.  For such columns, 
                  the dimension of entszs must be at least nrows. 
                  The size of null entries should be set to zero. 
 
                  For columns having fixed-size entries, the 
                  dimension of this array may be any positive value. 
 
   nlflgs         is an array of logical flags indicating whether 
                  the corresponding entries are null.  If the Ith 
                  element of nlflgs is SPICEFALSE, the Ith column entry 
                  defined by cvals and entszs is added to the 
                  current segment in the specified kernel file. 
 
                  If the Ith element of nlfgls is SPICETRUE, the 
                  contents of the Ith column entry are undefined. 
 
                  nlflgs is used only for columns that allow null 
                  values; it's ignored for other columns. 
 
   rcptrs         is an array of record pointers for the input 
                  segment.  This array is obtained as an output 
                  from ekifld_c, the routine called to initiate a 
                  fast write. 
 
   wkindx         is a work space array used for building a column 
                  index.  If the column is indexed, the dimension of 
                  wkindx_c must be at nrows, where nrows is the number 
                  of rows in the column.  If the column is not 
                  indexed, this work space is not used, so the 
                  dimension may be any positive value.

   routine. 
 
-Parameters
 
   None. 
 
-Exceptions
 
   1)  If handle is invalid, the error will be diagnosed by routines 
       called by this routine. 
 
   2)  If column is not the name of a declared column, the error
       SPICE(NOCOLUMN) will be signaled.
        
   3)  If column specifies a column of whose data type is not 
       character, the error SPICE(WRONGDATATYPE) will be 
       signalled. 
 
   4)  If the specified column already contains ANY entries, the 
       error will be diagnosed by routines called by this routine. 
 
   5)  If an I/O error occurs while reading or writing the indicated 
       file, the error will be diagnosed by routines called by this 
       routine. 
 
   6) If the string pointer for column is null, the error 
      SPICE(NULLPOINTER) will be signaled.
      
   7) If the input string column has length zero, the error 
      SPICE(EMPTYSTRING) will be signaled.
 
   8) If the string pointer for cvals is null, the error
      SPICE(NULLPOINTER) will be signaled.
     
   9) If the string length vallen is less than 2, the error 
      SPICE(STRINGTOOSHORT) will be signaled.
    
-Files
 
   See the EK Required Reading for a discussion of the EK file 
   format. 
 
-Particulars
 
   This routine operates by side effects:  it modifies the named 
   EK file by adding data to the specified column.  This routine 
   writes the entire contents of the specified column in one shot. 
   This routine creates columns much more efficiently than can be 
   done by sequential calls to ekacec_c, but has the drawback that 
   the caller must use more memory for the routine's inputs.  This 
   routine cannot be used to add data to a partially completed 
   column.

   1)  Suppose we have an E-kernel named order_db.ek which contains 
       records of orders for data products.  The E-kernel has a 
       table called DATAORDERS that consists of the set of columns 
       listed below: 
 
          DATAORDERS 
 
             Column Name     Data Type 
             -----------     --------- 
             ORDER_ID        INTEGER 
             CUSTOMER_ID     INTEGER 
             LAST_NAME       CHARACTER*(*) 
             FIRST_NAME      CHARACTER*(*) 
             ORDER_DATE      TIME 
             COST            DOUBLE PRECISION 
 
       The order database also has a table of items that have been 
       ordered.  The columns of this table are shown below: 
 
          DATAITEMS 
 
             Column Name     Data Type 
             -----------     --------- 
             ITEM_ID         INTEGER 
             ORDER_ID        INTEGER 
             ITEM_NAME       CHARACTER*(*) 
             DESCRIPTION     CHARACTER*(*) 
             PRICE           DOUBLE PRECISION 
 
 
       We'll suppose that the file ORDER_DB.EK contains two segments, 
       the first containing the DATAORDERS table and the second 
       containing the DATAITEMS table. 
 
       Below, we show how we'd open a new EK file and create the 
       first of the segments described above.

          At this point, arrays containing data for the 
          segment's columns may be filled in.  The names 
          of the data arrays are shown below.

             "COST"           costs 
       
       
          The null flags array indicates which entries are null. 
          It is ignored for columns that don't allow null 
          values.  In this case, only the COST column allows 
          nulls. 
          
          Fill in data arrays and null flag arrays here.  This code
          section would normally be replaced by calls to user functions
          returning column values.
          ./
          
          for ( i = 0;  i < NROWS;  i++ )
          {
             ordids[i]  =  i;
             cstids[i]  =  i*100;
             costs [i]  =  (SpiceDouble) 100*i;

          nlflgs[1] = SPICETRUE;
          
          
          /.
          The sizes array shown below is ignored for scalar 
          and fixed-size array columns, so we need not 
          initialize it.  For variable-size arrays, the 
          Ith element of the sizes array must contain the size 
          of the Ith column entry in the column being written. 
          Normally, the sizes array would be reset for each 
          variable-size column. 
       
          Add the columns of data to the segment.  All of the 
          data for each column is written in one shot. 
          ./
          ekacli_c ( handle,  segno,   "order_id",    ordids, 
                     sizes,   nlflgs,  rcptrs,        wkindx ); 
       
          ekacli_c ( handle,  segno,   "customer_id", cstids,  
                     sizes,   nlflgs,  rcptrs,        wkindx ); 
       
          ekaclc_c ( handle,  segno,   "last_name",   LNMLEN,
                     lnames,  sizes,   nlflgs,        rcptrs,  wkindx );

          ekacld_c ( handle,  segno,   "order_date",  ets,  
                     sizes,   nlflgs,  rcptrs,        wkindx );

          /.
          Complete the segment.  The rcptrs array is that 
          returned by ekifld_c. 
          ./
          ekffld_c ( handle, segno, rcptrs ); 
       
          /.
          At this point, the second segment could be 
          created by an analogous process.  In fact, the 
          second segment could be created at any time; it is 
          not necessary to populate the first segment with 
          data before starting the second segment. 
       
          The file must be closed by a call to ekcls_c. 
          ./
          ekcls_c ( handle ); 
       }

 
-Restrictions
 
   1)  Only one segment can be created at a time using the fast 
       write routines. 
 
   2)  No other EK operation may interrupt a fast write.  For 
       example, it is not valid to issue a query while a fast write 
       is in progress.

-Version

   -CSPICE Version 1.2.2, 14-AUG-2006   (EDW)

      Replace mention of ldpool_c with furnsh_c.

   -CSPICE Version 1.2.1, 09-JAN-2002 (NJB)

      Documentation change:  instances of the phrase "fast load"
      were replaced with "fast write."

      Const-qualified input array cvals.

   -CSPICE Version 1.1.0, 12-JUL-1998 (NJB)

       Bug fix:  now counts elements rather than rows for vector-valued
       columns.
       
       Bug fix:  now uses dynamically allocated array of type logical
       to interface with underlying f2c'd function ekaclc_.
       
       Now maps segno from C to Fortran range.
       
       Added "undef" of masking macro.  Changed input pointer types
       to pointers to const objects.
       
       Replaced eksdsc_ call with ekssum_c call.  This removes unsightly
       references to segment descriptor alignments.
       
       Fixed some chkout_c calls which referenced ekifld_c.
       
   -CSPICE Version 1.0.0, 25-FEB-1999 (NJB)
   
      Based on SPICELIB Version 1.0.0, 08-NOV-1995 (NJB)

-Index_Entries
 
   write entire character column to EK segment
