**
** Inputs:

**
** The path check flags II_CHK_PATHDIR and II_CHK_PATHPERM may be combined
** (bit wise); they include an implicit II_CHK_PATHCHAR. All path checks
** implicitly include an II_CHK_PATHLEN flag.
** Use the II_CHK_ALL flag as a convenient shorthand to perform each of the
** tests together.
** Specifying a flag of zero will check for the existence of the
** II_SYSTEM entry in the response file.
**
** Inputs:
** eflags Specifies the pre-installation checks to be performed.
** Can be a combination of the following
** 0 Test for existence of II_SYSTEM entry
** in response file
** II_CHK_HOSTNAME Verify characters in machine name
** II_CHK_OSVERSION Verify minimum OS version
** II_CHK_PATHCHAR Check characters used in II_SYSTEM
** II_CHK_PATHDIR Check II_SYSTEM path for a valid
** existing directory
** II_CHK_PATHPERM Check path write permissions
** II_CHK_PATHLEN Check length of path not exceeded
** II_CHK_USERNAME Verify characters in user name
** II_CHK_INSTCODE Verify characters of the configured
** instance code
** II_CHK_ALL Equivalent to II_PrecheckInstallation
** call.
** architecture The value of architecture is used only if the
** II_CHK_VERSION flag is set in the eflags field.
** If the II_CHK_VERSION flag is set
** Let the value of architecture be set as follows:
** Case:
** - II_DEFVER determines if the suitability of
** the internal Ingres platform architecture
** is appropriate for the operating architecture.
** - Determines if the suitability of the defined
** value of architecture is appropriate for the
** operating architecture.
** If the II_CHK_VERSION flag is not set
** Let the value of architecture be set to II_DEFVER.
**
** response_file Path to the Embedded Ingres response file
** For more information concerning response file options
** please see the Ingres Embedded Edition User Guide.
** This function requires valid values for the II_SYSTEM and
** charmap entries.
**
** Outputs:
** error_msg Message text for status. If the message text exceeds
** MAX_IIERR_LEN then the message is truncated to
** MAX_IIERR_LEN.
** Unchanged if II_SUCCESSFUL is returned.
**
** Returns:
** II_SUCCESSFUL The environment test completed successfully
** II_NULL_PARAM The parameters passed are invalid
** II_NO_INSTALL_PATH Error reading response file or no II_SYSTEM entry
** II_NO_CHAR_MAP Error reading response file or no II_CHARMAP entry
** II_CHARMAP_ERROR Error processing character mapping file
** II_GET_COMPUTER_FAIL Attempt to retrieve computer name failed
** II_INVALID_HOST Computer name contains illegal characters
** II_GET_HOST_FAILED Attempt to retrieve the network name failed
** II_INVALID_USER The username contains illegal characters
** II_UNMATCHED_NAME Computer name does not match network name
** II_OS_NOT_MIN_VERSION OS version does not meet the minimum requirement
** II_BAD_PATH The II_SYSTEM path is incorrectly formed
** II_INVAL_CHARS_IN_PATH The II_SYSTEM path contains illegal characters
** II_PATH_NOT_DIR The II_SYSTEM path does not contain a valid
** directory
** II_PATH_CANNOT_WRITE No write permission in the II_SYSTEM directory or
** a parent directory.
** II_PATH_EXCEEDED Length of the path exceeds permitted maximum
** II_INVALID_INSTANCECODE Instance code contains illegal characters
** II_INSTANCE_ERROR Error reading instance code or no instancecode
** entry.
**
** Example:
** # include "tngapi.h"
**
** # if defined(UNIX)
** II_CHAR reponsefile[] = {"./ingres.rsp"};
** # else
** II_CHAR reponsefile[] = {".\\ingres.rsp"};
** # endif

** II_CHAR error_msg[MAX_IIERR_LEN + 1] = { '\0' };
**
** if ((status = II_PrecheckInstallationEx( eflags, II_DEFARCH, responsefile,

**
** History:
** 07-Sep-2004 (fanra01)
** Created based on II_PrecheckInstallation.
** 30-Jun-2005 (fanra01)
** Moved and extended path validation into check_path function.
** 18-Aug-2005 (fanra01)
** Include path length check on character map file.
