Function Documentation

struct network_conn* plain_connect	(	char *	server,
		int	port
	)

Connect a plain TCP/IP socket to server:port.

Parameters

server	The server to connect to, either an IP or a hostname.
port	The servers port ( )

Returns

Pointer to a network_conn struct, or NULL in case of an error

Here is the call graph for this function:

Here is the caller graph for this function:

void plain_disconnect

(

struct network_conn *

nwc

)

Disconnect a connected plain TCP/IP socket.

After a call to plain_disconnect() all the memory assocatied to nwc is free'd, nwc may not be used anymore.

Parameters

nwc	The connection to disconnect

Here is the caller graph for this function:

int plain_recv	(	struct network_conn *	nwc,
		char *	buffer,
		size_t	buffer_len
	)

Receive a data from a connected plain TCP/IP socket.

TODO

Parameters

nwc	The connection to read from
buffer	The buffer receiving the read data
buffer_len	The size of the buffer

Returns

The byte or -1 on EOF

Here is the caller graph for this function:

int plain_recv_byte

(

struct network_conn *

nwc

)

Receive a single byte from a connected plain TCP/IP socket.

As soon as -1 is returned the underlying TCP/IP connection has been disconnected (for instance by the remote server). Any further call to plain_recv* will fail, so just call plain_disconnect() to free the data. "The horse is dead"

Parameters

nwc	The connection to read from

Returns

The byte or -1 on EOF
