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

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

.SH RETURN VALUE
Upon successful completion,
.BR gd_nfragments ()
returns the total number of format specification fragments which are present in
the dirfile.  On error, 
.BR gd_nfragments ()
returns zero and sets the dirfile error to a non-zero value.  Possible error
values are:
.TP 8
.B GD_E_BAD_DIRFILE
The supplied dirfile was invalid.
.PP
The dirfile error may be retrieved by calling
.BR gd_error (3).
A descriptive error string for the last error encountered can be obtained from
a call to
.BR gd_error_string (3).
