Class: Kgio::TCPServer

Inherits:

TCPServer

• Object
• TCPServer
• Kgio::TCPServer

Defined in:

ext/kgio/accept.c,
ext/kgio/accept.c

Overview

Kgio::TCPServer should be used in place of the plain TCPServer when kgio_accept and kgio_tryaccept methods are needed.

Instance Method Summary

• #kgio_accept(*args) ⇒ Object

  server = Kgio::TCPServer.new(‘0.0.0.0’, 80) server.kgio_accept -> Kgio::Socket or nil server.kgio_tryaccept -> Kgio::Socket or nil server.kgio_tryaccept(klass = MySocket) -> MySocket or nil.

• #kgio_tryaccept(*args) ⇒ Object

  server = Kgio::TCPServer.new(‘0.0.0.0’, 80) server.kgio_tryaccept -> Kgio::Socket or nil server.kgio_tryaccept(klass = MySocket) -> MySocket or nil server.kgio_tryaccept(nil, flags) -> Kgio::Socket or nil.

Instance Method Details

#kgio_accept(*args) ⇒ Object

server = Kgio::TCPServer.new(‘0.0.0.0’, 80) server.kgio_accept -> Kgio::Socket or nil server.kgio_tryaccept -> Kgio::Socket or nil server.kgio_tryaccept(klass = MySocket) -> MySocket or nil

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);
}

#kgio_tryaccept(*args) ⇒ Object

server = Kgio::TCPServer.new(‘0.0.0.0’, 80) server.kgio_tryaccept -> Kgio::Socket or nil server.kgio_tryaccept(klass = MySocket) -> MySocket or nil server.kgio_tryaccept(nil, flags) -> Kgio::Socket or nil

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.

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)
