fr_radius_client_bio_connect()

int fr_radius_client_bio_connect

(

fr_bio_packet_t *

bio

)

Try to connect a socket.

Calls fr_bio_fd_connect()

Parameters

bio	the packet bio

Returns

• 0 for "connected, can continue"
• fr_bio_error(IO_WOULD_BLOCK) for "not yet connected, please try again"
• <0 for other fr_bio_error()

fr_radius_client_fd_bio_cancel()

int fr_radius_client_fd_bio_cancel	(	fr_bio_packet_t *	bio,
		fr_packet_t *	packet
	)

Cancel one packet.

The packet can have a reply, or not. It doesn't matter.

This also frees any IDs associated with the packet.
