Function Documentation

int Xaccept	(	int	sockfd,
		struct sockaddr *	addr,
		socklen_t *	addrlen
	)

The Xaccept system call is is only valid with Xsockets created with the SOCK_STREAM transport type. It accepts the first available connection request for the listening socket, sockfd, creates a new connected socket, and returns a new Xsocket descriptor referring to that socket. The newly created socket is not in the listening state. The original socket sockfd is unaffected by this call.

Parameters

sockfd	an Xsocket previously created with the SOCK_STREAM type, and bound to a local DAG with Xbind()
addr	if non-NULL, points to a block of memory that will contain the address of the peer on return
addrlen	on entry, contains the size of addr, on exit contains the actual size of the address. addr will be truncated, if the size passed in is smaller than the actual size.

Note

See the man page for the standard accept() call for more details.

Returns

a non-negative integer that is the new Xsocket id

-1 on error with errno set to an error compatible with those returned by the standard accept call.

int Xaccept4	(	int	sockfd,
		struct sockaddr *	addr,
		socklen_t *	addrlen,
		int	flags
	)

The Xaccept4 system call is is only valid with Xsockets created with the SOCK_STREAM transport type. It accepts the first available connection request for the listening socket, sockfd, creates a new connected socket, and returns a new Xsocket descriptor referring to that socket. The newly created socket is not in the listening state. The original socket sockfd is unaffected by this call.

Parameters

sockfd	an Xsocket previously created with the SOCK_STREAM type, and bound to a local DAG with Xbind()
addr	if non-NULL, points to a block of memory that will contain the address of the peer on return
addrlen	on entry, contains the size of addr, on exit contains the actual size of the address. addr will be truncated, if the size passed in is smaller than the actual size.
flags	if SOCK_NONBLOCK is set, the new socket will be non-blocking. An error will be returned if any other bits in the flags are set.

Note

See the man page for the standard accept() call for more details.

Returns

a non-negative integer that is the new Xsocket id

-1 on error with errno set to an error compatible with those returned by the standard accept call.
