The SUN SparcWorks compiler uses pragma directives to mark initialization and cleanup functions of a library. If the module should also run under VxWorks, the function prototype should be declared with the help of the '__init__' and '__fini__' macros (see section VxWorks object modules).

If the GNU C/C++ compiler is used under Solaris, the macros '__init__' and '__fini__' should be sufficient (the pragma directives don't hurt, so they can be left there).

We recommend to always use the macro and the pragma directive together.

Example:

    __fini__(finiModule1);
    #pragma init(finiModule1)
    
    void finiModule1 (void) { ... }
