Remapping file names with MANIFEST.H

To conform to the MVS™ requirement that MVS data set names be eight characters or less in length, a file called MANIFEST.H remaps the RPC long names to eight-character derived names for internal processing.

The MANIFEST.H header file must be the first include file in the application, and it must be present at compile-time. If it is not included, the application will fail to link-edit. If the preprocessor macro MVS is defined when the RPC.H file is included, RPC.H will implicitly include MANIFEST.H.

Note: #define Resolve_Via_Lookup must be specified before #include manifest.h to enable the following socket calls: endhostent(), gethostent(), gethostbyaddr(), gethostbyname(), and sethostent().
