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,
gd_nfragments() returns zero and sets the dirfile error to a non-zero
value. Possible error values are:
- GD_E_BAD_DIRFILE
- The supplied dirfile was invalid.
The dirfile error may be retrieved by calling
gd_error(3). A descriptive
error string for the last error encountered can be obtained from a call to
gd_error_string(3).
