unsigned Eth_Get_Udp_Dest_Port(void);

Returns Returns the destination port of the received UDP packet.

Description The function returns the destination port of the received UDP packet. The second

information contained in the UDP packet header is the destination port (socket) to which

the packet is targeted.

Requires This function must be called in a proper sequence, i.e. immediately after calling the

Eth_Get_Udp_Source_Port function.

Example

udp_dest_port = Eth_Get_Udp_Dest_Port();

Prototype

unsigned Eth_Get_Udp_Source_Port(void);

Returns Returns the source port (socket) of the received UDP packet.

Description The function returns the source port (socket) of the received UDP packet. After the

reception of valid IP packet is detected and its type is determined to be UDP, the UDP

packet header must be interpreted. UDP source port is the first data in the UDP header.

Requires This function must be called in a proper sequence, i.e. immediately after interpretation

of the IP packet header (at the very beginning of UDP packet header retrieval).

Example

udp_source_port = Eth_Get_Udp_Source_Port();

Eth_Get_Udp_Source_Port
