Function Documentation

osmo_ss7_as_count_asp()

unsigned int osmo_ss7_as_count_asp

(

const struct osmo_ss7_as *

as

)

Determine amount of ASPs associated to an AS.

Parameters

[in]

as

Application Server.

Returns

number of ASPs associated to as

ss7_as_add_asp()

int ss7_as_add_asp	(	struct osmo_ss7_as *	as,
		struct osmo_ss7_asp *	asp
	)

Add given ASP to given AS.

Parameters

[in]	as	Application Server to which asp is added
[in]	asp	Application Server Process to be added to as

Returns

0 on success; negative in case of error

ss7_as_select_asp()

struct osmo_ss7_asp * ss7_as_select_asp	(	struct osmo_ss7_as *	as,
		const struct osmo_mtp_transfer_param *	mtp
	)

Select an AS to transmit a message, according to AS configuration and ASP availability.

Parameters

[in]

as

Application Server.

Returns

asp to send the message to, NULL if no possible asp found

This function returns NULL too if multiple ASPs would be selected, ie. AS is configured in broadcast mode and more than one ASP is configured.
