This function allocates a new control block. Returns NULL if there are no more control
blocks available.
Returns:
An allocated TCB or NULL if none available.
B.2.13 udpBind
tS8 udpBind( tUdpTcb* pTcb, tIPAddr* pIPAddr, tU16 port )
Bind a TCB to a port.
Parameters:
[in] pTcb - an allocated TCB that will be bound to a specific port.
[in] pIPAddr – the IP address to bind to. This parameter may be set to NULL if the
TCB should be bound to all interfaces.
[in] port - the port number to use or 0 (zero) if the stack should choose a port
number.
Returns:
One of the following error codes:
Possible error situations (what can be identified in an error code):
UDP_OK - no errors
UDP_NULL_POINTER - parameter pTcb was NULL.
UDP_PORT_IN_USE - port number is already assigned to a connection.
B.2.14 udpReceive
void udpReceive( tUdpTcb* pTcb, void (*pRecv)(tUdpTcb* pTcb,
tBuf* pBuf, tU16 len) )
This function registers a receive callback. The callback will be called whenever there is
data to receive on the connection. Parameters to the callback function are the control
block for the connection, a pointer to the buffer containing the data and length of the
data.
Parameters:
[in] pTcb - a bound control block
[in] pRecv - function pointer to the receive callback.
Parameters to (*pRecv):
[in] pTcb - control block for the connection.
[in] pBuf - pointer to the buffer containing data. A pointer to the actual data can be
retrieved by using the m_buf_get_data macro.
[in] len - length of data in bytes.
B.2.15 udpBufProcessed
void udpBufProcessed( tUdpTcb* pTcb, tBuf* pBuf )
