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 (32650-90144) 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.
