[2005-10-13 11:38:15] khayll at motoros dot hu 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 50 as sec it works. Seems like sec is used as usec, and usec has no effect. -- Edit this bug report at http://bugs.php.net/?id=34851edit=1
