Magic used to validate the type of network_conn.

Function Documentation

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

Connect an encrypted TCP/IP socket to server:port.

Parameters

server	The server to connect to, either an IP or a hostname.
port	The servers port (0 <= port <= 65536)

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 tls_disconnect

(

struct network_conn *

nwc

)

Here is the caller graph for this function:

bool tls_finalize

(

)

Free previous global initialization of TLS.

Returns

true in case of success, false otherwise

Here is the caller graph for this function:

bool tls_init

(

)

Global initialization of TLS.

This function is required to be called prior to the first call tls_connect(). Global initialization, such as loading the list of trusted CAs is performed here.

Returns

true in case of success, false otherwise
