Function Documentation

int rd	(	int	fd,
		char *	data,
		int *	len,
		int	maxlen
	)

Read a data segment from a network stream.

This function will block until the specified length has been received.

Parameters:

	fd	[in] file descriptor
	data	[out] buffer to store the read data
	len	[out] received length in bytes
	maxlen	[in] maximum length of data buffer in bytes

Returns:

received data length in bytes, or -1 on error.

int wt	(	int	fd,
		char *	data,
		int	len
	)

Write a data segment to a network stream.

Parameters:

	fd	[in] file descriptor
	data	[in] buffer that holds data to write
	len	[out] received length in bytes

Returns:

actually written data length in bytes, or -1 on error.

int ready_as_server

(

int

port_num

)

Prepare as a server creating a socket for client connection.

Parameters:

port_num

[in] network port to listen.

Returns:

socket descriptor, or -1 if failed to create socket, -2 if failed to bind, or -3 if failed to listen.

int accept_from

(

int

sd

)

Wait for a request from client.

This function blocks until a connection request comes.

Parameters:

sd

[in] listening server socket descpritor

Returns:

the connected socket descriptor.

Referenced by adin_tcpip_begin(), and main_module_loop().

int make_connection	(	char *	hostname,
		int	port_num
	)

Make a connection to a server.

Parameters:

	hostname	[in] server host (host name or numeric IP address)
	port_num	[in] port number

Returns:

new socket descriptor, -1 if fails to prepare socket, -2 if fails to connect, -3 if host name is wrong.

Definition at line 161 of file server-client.c.

int make_connection_unix

(

char *

address

)

Make a connection to a server using unix domain socket.

Parameters:

address

[in] unix domain socket address (path)

Returns:

new socket descriptor, -1 if fails to prepare socket, -2 if fails to connect.

Definition at line 244 of file server-client.c.

int close_socket

(

int

sd

)

Close socket.

Parameters:

sd

[in] socket descriptor to close

Returns:

0 on success, -1 on failure.

void cleanup_socket

(

)

Clean up socket data at program exit.
