gd_dirfilename(3) retrieve the name of a dirfile


#include <getdata.h>
const char *gd_dirfilename(DIRFILE *dirfile);


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).


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 sets the dirfile error to a non-zero value. Possible error values are:
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).
