NAME
       gd_nmfields_by_type -- report the number of fields of a given type in a dirfile

SYNOPSIS
       #include <getdata.h>

       unsigned int gd_nmfields_by_type(DIRFILE *dirfile, const char *parent, gd_entype_t type);

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

       The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).  The type argument should be  one	of
       the following symbols indicating the type of field to count:

	      GD_BIT_ENTRY, GD_CARRAY_ENTRY, GD_CONST_ENTRY, GD_DIVIDE_ENTRY, GD_INDEX_ENTRY, GD_LINCOM_ENTRY, GD_LINTERP_ENTRY,
	      GD_MULTIPLY_ENTRY, GD_PHASE_ENTRY, GD_POLYNOM_ENTRY, GD_RECIP_ENTRY, GD_SBIT_ENTRY, GD_STRING_ENTRY.

RETURN VALUE
       Upon successful completion, gd_nmfields_by_type() 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).
