int accept_cloexec_nonblock	(	int	fd,
		struct sockaddr *	address,
		size_t *	address_length_r
	)

Wrapper for accept(), which sets the CLOEXEC and the NONBLOCK flags (atomically if supported by the OS).

int close_socket

(

int

fd

)

Portable wrapper for close(); use closesocket() on WIN32/WinSock.

int dup_cloexec

(

int

oldfd

)

Wrapper for dup(), which sets the CLOEXEC flag on the new descriptor.

int open_cloexec	(	const char *	path_fs,
		int	flags,
		int	mode
	)

Wrapper for open(), which sets the CLOEXEC flag (atomically if supported by the OS).

int pipe_cloexec

(

int

fd[2]

)

Wrapper for pipe(), which sets the CLOEXEC flag (atomically if supported by the OS).

int pipe_cloexec_nonblock

(

int

fd[2]

)

Wrapper for pipe(), which sets the CLOEXEC flag (atomically if supported by the OS).

On systems that supports it (everybody except for Windows), it also sets the NONBLOCK flag.

ssize_t recvmsg_cloexec	(	int	sockfd,
		struct msghdr *	msg,
		int	flags
	)

Wrapper for recvmsg(), which sets the CLOEXEC flag (atomically if supported by the OS).

int socket_cloexec_nonblock	(	int	domain,
		int	type,
		int	protocol
	)

Wrapper for socket(), which sets the CLOEXEC and the NONBLOCK flag (atomically if supported by the OS).

int socketpair_cloexec	(	int	domain,
		int	type,
		int	protocol,
		int	sv[2]
	)

Wrapper for socketpair(), which sets the CLOEXEC flag (atomically if supported by the OS).

int socketpair_cloexec_nonblock	(	int	domain,
		int	type,
		int	protocol,
		int	sv[2]
	)

Wrapper for socketpair(), which sets the flags CLOEXEC and NONBLOCK (atomically if supported by the OS).
