| 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 udp framework define a function udp_loop that take as argument |
| a structure udp_ops (defined in include/net/udp.h) : |
| int (*prereq)(void *data); |
| int (*start)(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 = { |
| err = udp_loop(&udp_ops); |
