| 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); |
