gd_invalid_dirfile(3) GETDATA gd_invalid_dirfile(3)NAME
gd_invalid_dirfile -- obtain an pointer to an invalid DIRFILE object
SYNOPSIS
#include <getdata.h>
DIRFILE* gd_invalid_dirfile(void);
DESCRIPTION
The gd_invalid_dirfile() returns a pointer to a newly allocated, invalid DIRFILE object. Like any other DIRFILE object, the invalid
DIRFILE object should be de-allocated by calling gd_close(3) or gd_discard(3) when it is no longer needed.
The DIRFILE object returned may be passed to any other GetData function which requires one, but doing so will inevitably result in that
function failing with the GD_BAD_DIRFILE error.
A similar effect can be achieved by making an invalid gd_open(3) call, such as:
gd_open("", 0);
which also returns a pointer to an invalid DIRFILE object. The difference is that an invalid DIRFILE created in this way has a non-zero
dirfile error (obtainable with gd_error(3)), while the dirfile error of the invalid DIRFILE returned by gd_invalid_dirfile(3) is zero (in-
dicating success).
RETURN VALUE
This function always returns a pointer to a newly allocated, invalid DIRFILE object.

gd_dirfilename(3) GETDATA gd_dirfilename(3)NAME
gd_dirfilename -- retrieve the name of a dirfile
SYNOPSIS
#include <getdata.h>
const char *gd_dirfilename(const DIRFILE *dirfile);
DESCRIPTION
The gd_dirfilename() function queries a dirfile(5) database specified by dirfile and returns its name. The name of a dirfile is the path-
name passed to gd_cbopen() or gd_open() when the dirfile was opened.
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 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).
