class Kgio::TCPServer
Kgio::TCPServer should be used in place of the plain TCPServer when #kgio_accept and #kgio_tryaccept methods are needed.
Public Instance Methods
Initiates a blocking accept and returns a generic Kgio::Socket object with the kgio_addr attribute set to the IP address of the client on success.
On Ruby implementations using native threads, this can use a blocking accept(2) (or accept4(2)) system call to avoid thundering herds.
An optional klass
argument may be specified to override the
Kgio::Socket-class on a successful return value.
An optional flags
argument may also be specified.
flags
is a bitmask that may contain any combination of:
-
Kgio::SOCK_CLOEXEC - close-on-exec flag (enabled by default)
-
Kgio::SOCK_NONBLOCK - non-blocking flag (unimportant)
static VALUE tcp_accept(int argc, VALUE *argv, VALUE self) { struct sockaddr_storage addr; socklen_t addrlen = sizeof(struct sockaddr_storage); struct accept_args a; a.addr = (struct sockaddr *)&addr; a.addrlen = &addrlen; prepare_accept(&a, self, argc, argv); return my_accept(&a, 0); }
Initiates a non-blocking accept and returns a generic Kgio::Socket object with the kgio_addr attribute set to the IP address of the connected client on success.
Returns nil on EAGAIN, and raises on other errors.
