gd_dirfilename - Man Page

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).

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:


The supplied dirfile was invalid.

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


The function dirfilename() appeared in GetData-0.3.0.

In GetData-0.7.0, this function was renamed to gd_dirfilename().

In GetData-0.10.0, the error return from this function changed from -1 to a negative-valued error code.
