unlang_map_yield()

unlang_action_t unlang_map_yield	(	request_t *	request,
		map_proc_func_t	resume,
		unlang_map_signal_t	signal,
		fr_signal_t	sigmask,
		void *	rctx
	)

Yield a request back to the interpreter from within a module.

This passes control of the request back to the unlang interpreter, setting callbacks to execute when the request is 'signalled' asynchronously, or whatever timer or I/O event the module was waiting for occurs.

Note

The module function which calls unlang_module_yield should return control of the C stack to the unlang interpreter immediately after calling unlang_module_yield. A common pattern is to use return unlang_module_yield(...).

Parameters

[in]	request	The current request.
[in]	resume	Called on unlang_interpret_mark_runnable().
[in]	signal	Called on unlang_action().
[in]	sigmask	Set of signals to block.
[in]	rctx	to pass to the callbacks.

Returns

• UNLANG_ACTION_YIELD.
