wait_for_sync

Waits until this is synced for reporting the current time.

If timeout is CLOCK_TIME_NONE it will wait forever, otherwise it will time out after timeout nanoseconds.

For asynchronous waiting, the synced signal can be used.

This returns immediately with true if NEEDS_STARTUP_SYNC is not set on the clock, or if the clock is already synced.

Parameters:

this	a GstClock
timeout	timeout for waiting or CLOCK_TIME_NONE

Returns:

true if waiting was successful, or false on timeout
