SYNOPSIS
#include <getdata.h>

int get_fragment_index(const DIRFILE *dirfile, const char*field_code);
DESCRIPTION
get_fragment_index() function queries a dirfile(5) database specified by dirfile and returns the index number of the fragment defining the field specified by field_code. If field_code contains a representation suffix, it will be ignored.
RETURN VALUE
Upon successful completion, get_fragment_index() returns the requested fragment index. On error, get_fragment_index() returns -1 and sets the dirfile error a non-zero error value. Possible error values are:
GD_E_BAD_DIRFILE- The supplied dirfile was invalid.
GD_E_BAD_CODE- The field specified by field_code was not found in the database.
GD_E_BAD_REPR- The representation suffix specified in field_code was not recognised. The dirfile error may be retrieved by calling
get_error(3). A descriptive error string for the last error encountered can be obtained from a call toget_error_string(3).
