DESCRIPTION

Get information about the system.

RETURNS

Nothing.

NOTES

On the first call it creates cached values, so it doesn't have to determine them repeatedly. On Linux, the "/proc/cpuinfo" special file is used.

It creates a registry subhierarchy, looking like: "HARDWAREDESCRIPTIONSystemCentralProcessor<processornumber>Identifier (CPU x86)". Note that there is a hierarchy for every processor installed, so this supports multiprocessor systems. This is done like Win95 does it, I think.

It creates some registry entries in the environment part: "HKLMSystemCurrentControlSetControlSession ManagerEnvironment". These are always present. When deleted, Windows(tm) will add them again.

It also creates a cached flag array for IsProcessorFeaturePresent(3w).

IMPLEMENTATION

Defined in "winbase.h".
