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).

NAME

       gd_nmfields -- report the number of metafields in a dirfile

SYNOPSIS

       #include <getdata.h>

       unsigned int gd_nmfields(DIRFILE *dirfile, const char *parent);

DESCRIPTION

       The  gd_nmfields() function queries a dirfile(5) database specified by dirfile and returns the number of metafields defined in the database
       for the parent field specified by parent.

       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_nmfields() returns the number of defined metafields for the given parent.  On error,  it	returns  zero  and
       sets the dirfile error to a non-zero error value.  Possible error values are:

       GD_E_BAD_CODE
	       The supplied parent field code was not found, or referred to a metafield itself.

       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).
