osmo_sccp_user_sap_down()

int osmo_sccp_user_sap_down	(	struct osmo_sccp_user *	scu,
		struct osmo_prim_hdr *	oph
	)

Main entrance function for primitives from SCCP User.

Implies a msgb_free(oph->msg), otherwise the same as osmo_sccp_user_sap().

Parameters

[in]	scu	SCCP User sending us the primitive
[in]	oph	Osmocom primitive sent by the user

Returns

0 on success; negative on error

osmo_sccp_user_sap_down_nofree()

int osmo_sccp_user_sap_down_nofree	(	struct osmo_sccp_user *	scu,
		struct osmo_prim_hdr *	oph
	)

Main entrance function for primitives from SCCP User.

The caller is required to free oph->msg, otherwise the same as osmo_sccp_user_sap_down().

Parameters

[in]	scu	SCCP User sending us the primitive
[in]	oph	Osmocom primitive sent by the user

Returns

0 on success; negative on error
