Detailed Description

Field Documentation

◆ @235

union { ... }

◆ activity

The bridge channel thread activity.

Used by local channel optimization to determine if the thread is in an acceptable state to optimize.

Note
Needs to be atomically settable.

Definition at line 160 of file bridge_channel.h.

Referenced by bridge_channel_handle_write(), bridge_channel_wait(), optimize_lock_chan_stack(), and optimize_lock_peer_stack().

◆ alert_pipe

int alert_pipe[2]

Pipe to alert thread when frames are put into the wr_queue.

unsigned int binaural_pos_change

TRUE if a change of binaural positions has to be performed.
