◆ vlc_atomic_notify_all()

void vlc_atomic_notify_all ( void * addr )

Wakes up all thread on an address.

Wakes up all threads sleeping on the specified address (if any). Any thread sleeping within a call to vlc_atomic_wait() or vlc_atomic_timedwait() with the specified address as first call parameter will be woken up.

Parameters

addr	address identifying which threads to wake up

◆ vlc_atomic_notify_one()

void vlc_atomic_notify_one ( void * addr )

Wakes up one thread on an address.

Wakes up (at least) one of the thread sleeping on the specified address. The address must be equal to the first parameter given by at least one thread sleeping within the vlc_atomic_wait() or vlc_atomic_timedwait() functions. If no threads are found, this function does nothing.

Parameters

addr	address identifying which threads may be woken up

◆ vlc_atomic_timedwait()

int vlc_atomic_timedwait	(	void *	addr,
		unsigned	val,
		vlc_tick_t	deadline
	)

Waits on an address with a time-out.

This function operates as vlc_atomic_wait() but provides an additional time-out. If the deadline is reached, the thread resumes and the function returns.

Parameters

addr	address to check for
val	value to match at the address
deadline	deadline to wait until

Return values

0	the function was woken up before the time-out
ETIMEDOUT	the deadline was reached

◆ vlc_atomic_timedwait_daytime()

		time_t	deadline
	)

References unlikely.

◆ vlc_atomic_wait()

void vlc_atomic_wait	(	void *	addr,
		unsigned	val
	)

Waits on an address.

Puts the calling thread to sleep if a specific unsigned 32-bits value is stored at a specified address. The thread will sleep until it is woken up by a call to vlc_atomic_notify_one() or vlc_atomic_notify_all() in another thread, or spuriously.

If the value does not match, do nothing and return immediately.

Parameters
