gd_dirfilename3
Retrieve the name of a dirfile
Usage
#include <getdata.h>
const char *gd_dirfilename(DIRFILE *dirfile);
Overview
The gd_dirfilename() function queries a dirfile(5) database specified by dirfile and returns its name. The name of a dirfile is an absolute pathname which refers to the dirfile base directory.
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_dirfilename() returns a pointer to a constant string containing the pathname of the dirfile. On error, gd_dirfilename() 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:
.TP 8 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).
