NAME

       gd_nfragments — retrieve the number of format specification fragments in a dirfile

SYNOPSIS

       #include <getdata.h>

       int gd_nfragments(const DIRFILE *dirfile);

DESCRIPTION

       The  gd_nfragments()  function  queries  a dirfile(5) database specified by dirfile and returns the total
       number of parsed format specification fragments in the database.

       The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).

RETURN VALUE

       Upon successful completion, gd_nfragments() returns the total number of  format  specification  fragments
       which are present in the dirfile.

       On  error,  this  function return zero and store 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_BAD_DIRFILE
               The supplied dirfile was invalid.

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