Class synchronizer::Leader

class Leader

Public Functions

Leader(std::string memory_segment, bool sync_on_start = false)

Tools for setting a process managed by a Follower to run either asynchronously to the process managed by the leader (i.e.

both processes run in parallel ignoring each other) or to run synchronously to another process managed the Leader (i.e. the two processes run alternatively) At startup, the follower will init to async mode, and will switch to sync mode when the corresponding call to the start_sync of the leader is called. Note that as follower needs to be started before its leader, and can survive several leaders. param[in] memory_segment segment id of the shared memory shared between the leader and the follower

~Leader()

void start_sync(long int timeout_us = -1)

Request the leader and the follower to start running synchronously param[in] the timeout (in micro seconds) the leader should wait to get the acknowledgment from the follower the request to run sync has been received.

Infinite wait if negative.

void stop_sync()

Request the leader and follower to switch to async mode.

void pulse()

Either does nothing (async mode) or uses internally wait/notify functions to alternate run with the follower (sync mode)
