This function must be called when received data has been processed. If this function is
not called the received buffer will not be de-allocated.

Parameters:

[in] pTcb - control block for an established connection.

[in] pBuf - processed buffer.

B.2.16 udpSend

tS8 udpSend( tUdpTcb* pTcb, tIPAddr* pDestIP, tU16 destPort,
tU8* pData, tU16 len, void (*pBufSent)(void* pData) )

This function sends data through a connection.

A callback function (pBufSent) must be registered if the application needs to know when
the data has been sent from the stack, i.e. when the sent data can be deallocated.

Parameters:

[in] pTcb - bound control block for the connection.

[in] pDestIP - destination IP address.

[in] destPort - destination port number

[in] pData - data to send

[in] len - length of data

[in] pBufSent - function pointer to a buffer sent callback. Supplied with the callback
is a pointer to the sent data. This callback will be called when the data has been sent
from the stack. It will then be safe to de-allocate any allocated memory.

Parameters to (*pBufSent):

[in] pData - Pointer to data supplied with the send call.

Returns:

One of the following error codes:

Possible error situations (what can be identified in an error code):

UDP_OK - no errors

UDP_OUT_OF_BUF - out of buffers

B.2.17 udpClose

void udpClose( tUdpTcb* pTcb )
