Data Fields
const char *	name
	Value portion of val=param (if needsparam=1), or standalone identifier (if needsparam=0).
int	needsparam
	1 if value requires parameter, 0 if it must not have a parameter.
int(*	helper )(void *obj, yasm_valparam *vp, unsigned long line, void *data, uintptr_t arg)
	Helper callback function if name and parameter existence match.
size_t	off
	Offset added to data pointer passed into yasm_dir_helper() before data pointer is given to yasm_dir_help.helper().

Field Documentation

int yasm_dir_help::needsparam

1 if value requires parameter, 0 if it must not have a parameter.

Definition at line 253 of file valparam.h.

int(* yasm_dir_help::helper)(void *obj, yasm_valparam *vp, unsigned long line, void *data, uintptr_t arg)

Helper callback function if name and parameter existence match.

Parameters:

	obj	obj passed into yasm_dir_helper()
	vp	value/parameter
	line	line passed into yasm_dir_helper()
	data	data passed into yasm_dir_helper() plus yasm_dir_help.off offset
	arg	yasm_dir_help.arg argument

Returns:

-1 on error, 0 otherwise.

size_t yasm_dir_help::off

Offset added to data pointer passed into yasm_dir_helper() before data pointer is given to yasm_dir_help.helper().

This is so that a structure can be passed into yasm_dir_helper() and this can be an offsetof() to point the helper function to a specific structure member.
