NAME

       gd_dirfilename — retrieve the name of a Dirfile

SYNOPSIS

       #include <getdata.h>

       const char *gd_dirfilename(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 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:

       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).

HISTORY

       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.
