Parameters
Return Values
Returns TRUE if function succeeds. Returns FALSE if the function fails.
GetLastError() may be used to get the extended error value.
GetLastError() may be used to get the extended error value.
lpInBuf
Should be set to NULL.
nInBufSize
Should be set to zero.
lpOutBuf
Should be a pointer to the PROCESSOR_INFO structure. Its
structure stores information describing the CPU more descriptively.
