Differences between <PMWSOCK.H> and Standard <WINSOCK.H> Header Files

Following are the differences between <PMWSOCK.H> and standard <WINSOCK.H> header files:

<PMWSOCK.H> does not include (with #include) any header files.
The keyword FAR has been removed from all functions and pointers.
The keyword PASCAL has been removed from all of the prototypes and replaced with APIENTRY.
The FARPROC type in the WSASetBlockingHook prototype has been replaced with PFN.
The hostent, netent, servent, and protoent structures had several entries that were defined as "short;" these have been widened to "int." The two fields of the linger structure have been widened from "u_short" to "int." These changes were made to comply with the definitions in the BSD header files.
A bug in the IN_CLASSC macro has been corrected.
The CONST keyword for the buf parameter of the prototype for WSAAsyncGetHostByAddr has been removed (it was an error).
