Course overview

Through a series of lectures and labs, you are taught how to use both the C compiler and the native mode C compiler used with HP NonStop™ servers, how to take advantage of various extensions, and how to interface with Guardian system procedures. In learning to use those compilers, you will become familiar with various aspects of the unique C run-time environment such as memory model issues, diagnostics, special debugging issues, and the retrieval of specific run-time and environment information. Prior C knowledge is essential.

  • ANSI/ISO C Programming experience
  • Recommended: Experience with the Inspect or Native Inspect symbolic debugger
  • Recommended: TAL programming experience


  • System analysts
  • System programmers
