socket_listen
Description
bool socket_listen ( resource socket [, int backlog] )
After the socket socket has been created
using socket_create() and bound to a name with
socket_bind(), it may be told to listen for incoming
connections on socket.
A maximum of backlog incoming connections will be
queued for processing. If a connection request arrives with the queue
full the client may receive an error with an indication of
ECONNREFUSED, or, if the underlying protocol supports
retransmission, the request may be ignored so that retries may succeed.
Notatka: The maximum number passed to the
backlogparameter highly depends on the underlying platform. On Linux, it is silently truncated to SOMAXCONN. On win32, if passed SOMAXCONN, the underlying service provider responsible for the socket will set the backlog to a maximum reasonable value. There is no standard provision to find out the actual backlog value on this platform.
socket_listen() is applicable only to sockets of type SOCK_STREAM or SOCK_SEQPACKET.
Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki. The error code can be retrieved with socket_last_error(). This code may be passed to socket_strerror() to get a textual explanation of the error.
See also socket_accept(), socket_bind(), socket_connect(), socket_create() and socket_strerror().
