- Udp framework
- The udp framework is build on top of network framework and is designed
- to define new protocol or new command based on udp without modifying
- the network framework.
- The udp framework define a function udp_loop that take as argument
- a structure udp_ops (defined in include/net/udp.h) :
- struct udp_ops {
- int (*prereq)(void *data);
- int (*start)(void *data);
- void *data;
- };
- The callback prereq define if all the requirements are
- valid before running the network/udp loop.
- The callback start define the first step in the network/udp loop,
- and it may also be used to configure a timemout and udp handler.
- The pointer data is used to store private data that
- could be used by both callback.
- A simple example to use this framework:
- static struct udp_ops udp_ops = {
- .prereq = wmp_prereq,
- .start = wmp_start,
- .data = NULL,
- };
- ...
- err = udp_loop(&udp_ops);
