* 1. Define the structure to avoid conflict with winsock's structure.
|
|
* 2. And the same time, in the "af_inet_winsock.c" shouldn't include header files aboult "sal",
|
|
* if include header files aboult "sal", the complier in the vs2012 will give me "structure redefined error".
|
|
*
|
|
* So, i define the same structure with "sal" but not include header files aboult "sal".
|
|
* The same sturcture means the same memory in the system. I can offer wonderful compatibility with "sal" ,"winsock", "lwip" and so on.
|
|
*
|
|
*
|
|
* Aross the way, "WinSock2.h" only be included in the "af_inet_winsock.c", the more software packages aboult network can
|
|
* work that useless modification is required for "winsock".
