/* TBL_Select
**
** Purpose:
** This function selects some number of records (possibly zero),
** that match the criteria specifications given in the input
** parameter criteriaList.
**
** Parameter Dictionary:
** TBL_HANDLE **handle: The pointer for the database/table pair
** to be accessed. This table must be open.
** TBL_CRITERIA *criteriaList: Contains a list of the criteria
** to use when selecting records from the specified table.
** A null list implies that all records will be selected.
** TBL_FIELD *fieldList: Contains a list of the fields to be
** retreived from each record that matches the criteria
** specification. It is an error to specify a null
** fieldList.
** int *count: Contains a number that represents the total number
** of records retreived by this particular select. If this
** parameter is null, then an internal counter is used and
** the final count will not be returned when the select
** finishes.
** CONDITION (*callback)(): The callback function invoked whenever
** a new record is retreived from the database. It is
** invoked with parameters as described below.
** void *ctx: Ancillary data passed through to the callback function
** and untouched by this routine.
**
** Return Values:
** TBL_NORMAL: normal termination.
** TBL_BADHANDLE: The handle passed to the routine was invalid.
** TBL_DBNOEXIST: The database specified does not exist.
** TBL_NOFIELDLIST: A null field list pointer (fieldList *) was
** specified.
** TBL_SELECTFAILED: The select operation failed most probably from
** a bad specification in the fieldList or criteriaList. This
** return is not the same as a valid query returning no records.
** This error return could result from a misspelled keyword, etc.
** TBL_EARLYEXIT: The callback routine returned something other than
** TBL_NORMAL which caused this routine to cancel the remainder
** of the database operation and return early.
**
** Algorithm:
** As each record is retreived from the
** database, the fields requested by the user (contained in
** fieldList), are filled with the informatiton retreived from
** the database and a pointer to the list is passed to the
** callback routine designated by the input parameter callback.
** The callback routine is invoked as follows:
**
** callback(fieldList *fieldList, long count, void *ctx)
**
** The count contains the number of records retreived to this point.
** ctx contains any additional information the user originally passed
** to this select function. If callback returns any value other
** than TBL_NORMAL, it is assumed that this function should terminate
** (i.e. cancel the current db operation), and return an abnormal
** termination message (TBL_EARLYEXIT) to the routine which
** originally invoked the select.

/* TBL_NextUnique
**
** Purpose:
** This routine retrieves the next unique number from a predefined table.
**
** Parameter Dictionary:
** TBL_HANDLE **handle: The pointer for the database/table pair
** to be accessed for modification. This table must be open.
** char *name : The name of the unique variable to access.
** int *unique: Contains the next unique number in the sequence upon
** return.
**
** Return Values:
** TBL_NORMAL: normal termination.
** TBL_BADHANDLE: The handle passed to the routine was invalid.
** TBL_DBNOEXIST: The database specified does not exist.
** TBL_SELECTFAILED: The unique number name could not be found.
** TBL_UPDATEFAILED: The unique number could not be incremented.
**
** Notes:
** Nothing unusual.
**
** Algorithm:
** The unique number associated with "name" in the opened table is
** retrieved and passed back to the user in "unique". This number is
** then incremented (by one) and placed back in the table in preparation
** for the next call to this routine.
