Bug description: SO_RECVTIMEO sec stands for usec!!!! and usec has no effect!
Description:
------------
I tried to set a receive timeout for a socket, but found out that sec is
used as usec, and usec is in fact ignored!
Reproduce code:
---------------
using a modbus device with "address" address, sorry i cannot make it
available on the net
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec"=>0,
"usec"=>500));
socket_connect($socket, "address", "502");
socket_write($this->socket, $data, strlen($data));
socket_read($this->socket, 512, PHP_BINARY_READ);
Expected result:
----------------
expected to read some data or give a timeout error.
Actual result:
--------------
code hangs, so i figured out, that usec has no effect, then i tried 1 sec
as timeout, code began to work, but kept reporting timeout, so i figured
out if i try a value like 500000 as sec it works. Seems like sec is used
as usec, and usec has no effect.
