Differences between and Standard 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).
