Guardian API Programming for HP NonStop Systems

( Duration: 5 Days )

The Guardian API Programming for HP NonStop Systems training course is for C, TAL, and pTAL developers. Learn how to use the Guardian Application Program Interface (API) to obtain operating system services including interprocess communication, process creation, Enscribe file access, and more.

By attending Guardian API Programming for HP NonStop Systems workshop, delegates will learn to:

  • Code for interprocess communication
  • Develop applications that access Enscribe files
  • Handle terminal input and output
  • Identify different types of system messages
  • Create and manage new processes
  • Available timing facilities
  • Know how nowait I/O can be used to improve application performance

  • TAL/pTAL Programming or C Programming in the Guardian Environment

This Guardian API Programming for HP NonStop Systems class is recommended for:

  • Systems programmers
  • Application programmers
  • Programmer analysts
