Function Documentation

sock_init()

int sock_init	(	SOCKINFO *	info,
		SOCKET	sockfd
	)

Assign the passed in socket descriptor to socket descriptor in the SOCKINFO structure.

Returns

Integer:

• UPNP_E_SUCCESS
• UPNP_E_OUTOF_MEMORY
• UPNP_E_SOCKET_ERROR

Parameters

[out]	info	Socket Information Object.
[in]	sockfd	Socket Descriptor.

Definition at line 440 of file sock.cpp.

sock_init_with_ip()

int sock_init_with_ip	(	SOCKINFO *	info,
		SOCKET	sockfd,
		struct sockaddr *	foreign_sockaddr
	)

Calls the sock_init function and assigns the passed in IP address and port to the IP address and port in the SOCKINFO structure.

Returns

Integer:

• UPNP_E_SUCCESS
• UPNP_E_OUTOF_MEMORY
• UPNP_E_SOCKET_ERROR

Parameters

[out]	info	Socket Information Object.
[in]	sockfd	Socket Descriptor.
[in]	foreign_sockaddr	Remote socket address.

sock_ssl_connect()

int sock_ssl_connect

(

SOCKINFO *

info

)

Associates an SSL object with the socket and begins the client-side SSL/TLS handshake.

Returns

Integer:

• UPNP_E_SUCCESS
• UPNP_E_SOCKET_ERROR

Parameters

[out]

info

Socket Information Object.

Definition at line 469 of file sock.cpp.

Here is the caller graph for this function:

sock_destroy()

int sock_destroy	(	SOCKINFO *	info,
		int	ShutdownMethod
	)

Shutsdown the socket using the ShutdownMethod to indicate whether sends and receives on the socket will be dis-allowed.

After shutting down the socket, closesocket is called to release system resources used by the socket calls.

Returns

Integer:

• UPNP_E_SOCKET_ERROR on failure.
• UPNP_E_SUCCESS on success.

Parameters

[in,out]	info	Socket Information Object.
[in]	ShutdownMethod	How to shutdown the socket. Used by sockets's shutdown().

sock_read()

int sock_read	(	SOCKINFO *	info,
		char *	buffer,
		size_t	bufsize,
		int *	timeoutSecs
	)

Reads data on socket in sockinfo.

Returns

Integer:

• numBytes - On Success, no of bytes received.
• UPNP_E_TIMEDOUT - Timeout.
• UPNP_E_SOCKET_ERROR - Error on socket calls.

Parameters

[in]	info	Socket Information Object.
[out]	buffer	Buffer to get data to.
[in]	bufsize	Size of the buffer.
[in,out]	timeoutSecs	timeout value.
