4.2.2. GetSystemInfo
Get information about the system.
Prototype:
Parameters:
Return Value:
A SYSINFO structure has the following layout:
typedef struct
{
} SYSINFO;
The SYSINFO structure contains the version of the Power Manager and the version of the Platform Support
component as zero-terminated strings.
