1Udp framework
2
3The udp framework is build on top of network framework and is designed
4to define new protocol or new command based on udp without modifying
5the network framework.
6
7The udp framework define a function udp_loop that take as argument
8a structure udp_ops (defined in include/net/udp.h) :
9
10struct udp_ops {
11	int (*prereq)(void *data);
12	int (*start)(void *data);
13	void *data;
14};
15
16The callback prereq define if all the requirements are
17valid before running the network/udp loop.
18
19The callback start define the first step in the network/udp loop,
20and it may also be used to configure a timemout and udp handler.
21
22The pointer data is used to store private data that
23could be used by both callback.
24
25A simple example to use this framework:
26
27static struct udp_ops udp_ops = {
28	.prereq = wmp_prereq,
29	.start = wmp_start,
30	.data = NULL,
31};
32
33...
34
35err = udp_loop(&udp_ops);
