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 after each ff_network_wait_fd call

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