NAME

       gd_raw_filename — retrieve the pathname of a binary file in a Dirfile

SYNOPSIS

       #include <getdata.h>

       char *gd_raw_filename(DIRFILE *dirfile, const char *field_code);

DESCRIPTION

       The  gd_raw_filename()  function  reports  the  pathname  of  the file backing the RAW field specified by
       field_code in the dirfile specified by dirfile.  If field_code contains a valid representation suffix, it
       will be ignored.

RETURN VALUE

       On success, gd_raw_filename() returns the full pathname of the binary file associated with the  specified
       field  in a newly-allocated buffer.  By default, this buffer is allocated with malloc(3), but a different
       memory manager may be specified by calling gd_alloc_funcs(3) before calling this function.  The caller is
       responsible for deallocating the returned buffer.

       On error, this function returns NULL and stores a negative-valued error code in the DIRFILE object  which
       may be retrieved by a subsequent call to gd_error(3).  Possible error codes are:

       GD_E_ALLOC
               The library was unable to allocate memory.

       GD_E_BAD_CODE
               The field specified by field_code was not found.

       GD_E_BAD_DIRFILE
               The supplied dirfile was invalid.

       GD_E_BAD_FIELD_TYPE
               The field specified by field_code was not a RAW field.

       GD_E_UNKNOWN_ENCODING
               The  encoding scheme of the specified field could not be determined or was not understood by Get‐
               Data.

       A descriptive error string for the error may be obtained by calling gd_error_string(3).

HISTORY

       The get_raw_filename() function appeared in GetData-0.4.2.  Memory for the string it returned was managed
       by GetData.

       In GetData-0.7.0, this function was renamed to gd_raw_filename().

       In GetData-0.8.0, the returned string changed to a malloc'd buffer, and the  responsibility  for  freeing
       the buffer passed to the caller.
