int ff_network_init ( void  )
int ff_network_wait_fd ( int  fd,
int  write 
)
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.

Parameters
fdSocket descriptor
writeSet 1 to wait for socket able to be read, 0 to be written
timeoutTimeout interval, in microseconds. Actual precision is 100000 mcs, due to ff_network_wait_fd usage
int_cbInterrupt 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

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.

Parameters
timeoutTimeout in microseconds. Maybe have lower actual precision.
int_cbInterrupt callback, is checked regularly.
Returns
AVERROR(ETIMEDOUT) if timeout expirted, AVERROR_EXIT if interrupted by int_cb

timeoutPolling timeout in milliseconds.
hURLContext providing interrupt check callback and logging context.
will_try_nextWhether the caller will try to connect to another address for the same host name, affecting the form of logged errors.
