Routine Description:
|
|||
|
|
|
|||
|
|
This routine will return the data for the processor object
|
|||
|
|
|
|||
|
|
Arguments:
|
|||
|
|
|
|||
|
|
IN OUT LPVOID *lppData
|
|||
|
|
IN: pointer to the address of the buffer to receive the completed
|
|||
|
|
PerfDataBlock and subordinate structures. This routine will
|
|||
|
|
append its data to the buffer starting at the point referenced
|
|||
|
|
by *lppData.
|
|||
|
|
OUT: points to the first byte after the data structure added by this
|
|||
|
|
routine. This routine updated the value at lppdata after appending
|
|||
|
|
its data.
|
|||
|
|
|
|||
|
|
IN OUT LPDWORD lpcbTotalBytes
|
|||
|
|
IN: the address of the DWORD that tells the size in bytes of the
|
|||
|
|
buffer referenced by the lppData argument
|
|||
|
|
OUT: the number of bytes added by this routine is writted to the
|
|||
|
|
DWORD pointed to by this argument
|
|||
|
|
|
|||
|
|
IN OUT LPDWORD NumObjectTypes
|
|||
|
|
IN: the address of the DWORD to receive the number of objects added
|
|||
|
|
by this routine
|
|||
|
|
OUT: the number of objects added by this routine is writted to the
|
|||
|
|
DWORD pointed to by this argument
|
|||
|
|
|
|||
|
|
Returns:
|
|||
|
|
|
|||
|
|
0 if successful, else Win 32 error code of failure
