Function Documentation

stwritestr()

int stwritestr	(	int	sfd,
		const char *	str
	)

Write a string to socket

streadstr()

int streadstr	(	int	sfd,
		char **	str
	)

Read a string from socket

stwritestrarr()

int stwritestrarr	(	int	sfd,
		const char *const *	str,
		int	nstr
	)

Write a string array to socket

streadstrarr()

int streadstrarr	(	int	sfd,
		char ***	str,
		int *	nstr
	)

Read a string array from socket

stwritefd()

int stwritefd	(	int	sfd,
		int	fd
	)

Wrie a file descriptor to socket. Transfer a open file (socket) descriptor to another process in the same hosts. sfd has to be a AF_UNIX socket.

streadfd()

int streadfd	(	int	sfd,
		int *	fd
	)

Read a file descriptor from socket. Use with stwritefd();

udp_send()

int udp_send	(	udp_t *	info,
		void *	buf,
		size_t	len,
		int	counter
	)

Use UDP socket to send data reliably. Status is checked.

udp_recv()

int udp_recv	(	udp_t *	info,
		void **	pbuf,
		size_t *	len
	)

Use UDP socket to receive data reliably. if counter
