php_stream_sock_open_unix -- Open a Unix domain socket and convert into a streamDescription
php_stream * php_stream_sock_open_unix ( const char * path, int pathlen, int persistent, struct timeval * timeout )php_stream_sock_open_unix() attempts to open the Unix domain socket specified by path. pathlen specifies the length of path. If timeout is not NULL, it specifies a timeout period for the connection attempt. persistent indicates if the stream should be opened as a persistent stream. Generally speaking, this parameter will usually be 0.
注: This function will not work under Windows, which does not implement Unix domain sockets. A possible exception to this rule is if your PHP binary was built using cygwin. You are encouraged to consider this aspect of the portability of your extension before it's release.
注: This function treats path in a binary safe manner, suitable for use on systems with an abstract namespace (such as Linux), where the first character of path is a NUL character.
