status.i4.v = structure_field_data(name.i1a.r, num_fields.i4.r,

	This routine returns field data for a named structure.
	A value of NULL can be passed for any of the returned values
	that are not needed.

	name		null terminated structure name
			(Note: The name format is [{class}.]{struct}.)
	num_fields	returned number of fields
	field_data	returned array of field data
			(array of structures of type STRUCT_FIELD_DATA)
			(The memory for this array is allocated by this
			 routine and should NOT be freed by the caller.)

	This function returns status values as follows:

	OK			success
	CLIB_MEMFAIL		dynamic memory allocation failed
	CLIB_NO_SUCH		structure name was not found

	This function requires the following include files:

	cbslib_h, cns_data_structs_h, acnet_errors_h
