- # user-interfaces Names of interfaces to put user stubs in for.
- # server-interfaces Names of interfaces to put server stubs in for.
- # interface-library Name of interface library to build and install.
- # This file sets:
- # interface-headers Names of generated interface header files.
- # interface-routines Names of generated interface routines.
- # All user stubs are put in individual files, prefixed with RPC_ (and the
- # function names prefixed with __), and a symbol-alias to the un-__'d form
- # generated; header for both is put in foo.h. Server interfaces are
- # written to foo_server.c and foo_server.h; the server functions are called
- # _S_rpcname.
