What Is an Intrinsic?

The term intrinsic refers to any external system or subsystem. However, under MPE/iX this term has a more specific meaning. To qualify as a true Hewlett-Packard documented and user-callable intrinsic, it must meet the following criteria:

An intrinsic is a Hewlett-Packard supported external interface to an operating system or subsystem service.
An intrinsic performs type and bounds checks on parameter values before it uses them, thus protecting the operating system and the user from one another.
An intrinsic is documented in a Hewlett-Packard manual.
If an intrinsic is enhanced, its interface, capabilities, and feature set remain backward compatible.
A process may call an intrinsic from any Hewlett-Packard supported programming language.
An intrinsic differs from other system library procedures

Hewlett-Packard subsystems and applications can also provide interfaces that meet the definition of an intrinsic. Refer to the MPE/iX Documentation Guide for further information.




	NOTE: You can define routines for access as if they were intrinsics and place them in new or existing intrinsic files and libraries.
