Detailed Description

Function Documentation

xbt_socket_t gras_socket_server ( unsigned short port )

Simply create a server socket (to ear from remote hosts speaking to you)

In real life, you'll get a TCP socket.

xbt_socket_t gras_socket_client_ext	(	const char *	host,
		unsigned short	port,
		unsigned long int	buf_size,
		int	measurement
	)

Create a client socket, full interface to all relevant settings.

Parameters

host,:	who you want to connect to
port,:	where you want to connect to on this host
buf_size,:	size of the buffer (in bytes) on the socket (for TCP sockets only). If 0, a sain default is used (32k, but may change)
measurement,:	whether this socket is meant to convey measurement (if you don't know, use 0 to exchange regular messages)

In real life, you'll get a TCP socket.

xbt_socket_t gras_socket_server_ext	(	unsigned short	port,
		unsigned long int	buf_size,
		int	measurement
	)

Create a server socket, full interface to all relevant settings.

Parameters

port,:	port on which you want to listen
buf_size,:	size of the buffer (in byte) on the socket (for TCP sockets only). If 0, a sain default is used (32k, but may change)
measurement,:	whether this socket is meant to convey measurement (if you don't know, use 0 to exchange regular messages)

In real life, you'll get a TCP socket.

xbt_socket_t gras_socket_server_range	(	unsigned short	minport,
		unsigned short	maxport,
		unsigned long int	buf_size,
		int	measurement
	)

Opens a server socket on any port in the given range.

Parameters

minport,:	first port we will try
maxport,:	last port we will try
buf_size,:	size of the buffer (in byte) on the socket (for TCP sockets only). If 0, a sain default is used (32k, but may change)
measurement,:	whether this socket is meant to convey measurement (if you don't know, use 0 to exchange regular messages)

If none of the provided ports works, raises the exception got when trying the last possibility
