xua_find_as_for_asp()

int xua_find_as_for_asp	(	struct osmo_ss7_as **	as,
		const struct osmo_ss7_asp *	asp,
		const struct xua_msg_part *	rctx_ie
	)

Find the AS for given ASP + optional routing context IE.

if rctx_ie == NULL, we assume that this ASP is only part of a single AS; if rctx_ie is given, then we look-up the ASP based on the routing context, and verify that this ASP is part of it.

Parameters

[out]	as	caller-provided address-of-pointer to store the found AS
[in]	asp	ASP for which we want to look-up the AS
[in]	rctx_ie	routing context IE (may be NULL) to use for look-up

Returns

0 in case of success; {M3UA,SUA}_ERR_* code in case of error.
