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.  Notably, 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).
