PM Library Reference
This section contains the function and data structure references for the
Portability Manager (PM) library used by the SciTech SNAP Graphics
Architecture. The PM library provides a suite of functions used by the
Binary Portable SNAP drivers, which abstract the Binary Portable driver
code from operating system specific functions. There are versions of
the PM library for every supported Operating System and target
environment that provides the interface layer to between the Binary
Portable device drivers and the target Operating System platform.
Porting the SciTech SNAP drivers to a new Operating System is simply a
matter of developing a new version of the PM library for that Operating
System. This reference is intended primarily as a reference for
developers porting the PM library to new platforms; application
developers should generally not use the PM library functions directly.
