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.

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_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

Parameters
fdFirst argument of bind().

addrlenThird argument of bind().
Returns
0 on success or an AVERROR on failure.

Poll for a single connection on the passed file descriptor.

Parameters
fdThe listening socket file descriptor.
timeoutPolling timeout in milliseconds.
hURLContext providing interrupt check callback and logging context.
Returns
A non-blocking file descriptor on success or an AVERROR on failure.

Connect to a file descriptor and poll for result.

Parameters
fdFirst argument of connect(), will be set as non-blocking.
addrSecond argument of connect().
addrlenThird argument of connect().
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.
Returns
0 on success, AVERROR on failure.
