ff_network_wait_fd_timeout()

int ff_network_wait_fd_timeout	(	int	fd,
		int	write,
		int64_t	timeout,
		AVIOInterruptCB *	int_cb
	)

This works similarly to ff_network_wait_fd, but waits up to 'timeout' microseconds Uses ff_network_wait_fd in a loop.

Socket descriptor Set 1 to wait for socket able to be read, 0 to be written Timeout interval, in microseconds. Actual precision is 100000 mcs, due to ff_network_wait_fd usage

Parameters

int_cb

Interrupt callback, is checked before each ff_network_wait_fd call

Returns

0 if data can be read/written, AVERROR(ETIMEDOUT) if timeout expired, or negative error code

ff_network_sleep_interruptible()

int ff_network_sleep_interruptible	(	int64_t	timeout,
		AVIOInterruptCB *	int_cb
	)

Waits for up to 'timeout' microseconds.

If the usert's int_cb is set and triggered, return before that. Timeout in microseconds. Maybe have lower actual precision.

Parameters

int_cb

Interrupt callback, is checked regularly.

Returns

AVERROR(ETIMEDOUT) if timeout expirted, AVERROR_EXIT if interrupted by int_cb
