Yes, which is correct. Therefore, a C program that reports "exit(0)" is
portable to any OS, regardless of "whatevver [sic] the OS s [sic] custom
is." For instance:

     exit(int ret_code)
     {
        if (ret_code==0) ret_code=VMS_SUCCESS_CODE;

        /* do other stuff, then terminate */
     }


Best regards,
