pdwSize
A pointer to a caller allocated DWORD whose value represents the
number of bytes at pvData. Upon success, dwSize returns the number
of bytes from the buffer used for a set.
pvData
A pointer to a caller allocated buffer, which contains the data values
for the selected parameter.
Return Values:
Return values are common for both Set and Get functions. See Get/Set
System Parameter - Return Codes above.
Remarks:
The buffer at *pvData must be large enough to contain the
information requested and must be aligned as required. For example,
if the data in *pvData is expected to be a DWORD value, then *pvData
MUST be DWORD aligned.
Please refer to System Parameters on page 42 for the data types
associated with the various writeable parameters.
Portability:
Please refer to System Parameters above for an enumeration of which
parameters are supported on the platforms.
Requirements:
System Timers The platform hardware provides timers of varying precision,
flexibility, and range. Some of these timers may be used for other
operating-system level purposes such as the reschedule timer
interrupt. However, one or more timers are available for
general-purpose use to application programs. The timers are typically
called user timers and can be configured for one-shot or periodic
operation.
