If the Pathmaker product does not encounter any errors during generation or
compilation, the message Generation successful is displayed in the Last
Attempted Generation Message field the next time you list the Service Definition
screen for this service.
The Pathmaker product uses the generated source file as the primary input file when
compiling a C service. C services can be generated and compiled separately outside of
any server or they can be generated and compiled as part of a server generation and
compile operation. In either case, a separate nonrunnable object file is created for each
C service compiled. Figure 4-6 illustrates the contents of a generated C service.
