gd_nfields

gd_nfields(3)							      GETDATA							     gd_nfields(3)

NAME

       gd_nfields -- report the number of fields in a dirfile

SYNOPSIS

       #include <getdata.h>

       unsigned int gd_nfields(DIRFILE *dirfile);

DESCRIPTION

       The gd_nfields() function queries a dirfile(5) database specified by dirfile and returns the number of fields defined in the database.  No-
       tably, this count does not include /META fields.

       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_nfields() returns the number of defined fields in the dirfile.  On error,  it  returns  zero  and  sets  the
       dirfile error to a non-zero error 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).
