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 after 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_listen_bind ( int  fd,
const struct sockaddr *  addr,

Bind to a file descriptor and poll for a connection.

Parameters
fdFirst argument of bind().
addrSecond argument of bind().
addrlenThird argument of bind().
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.

int ff_listen_connect ( int  fd,
const struct sockaddr *  addr,

)

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.
Returns
0 on success, AVERROR on failure.
