Parameters

action  SystemParametersActionFlags

The system-wide parameter to be retrieved or set.

uiParam  UInt32

A parameter whose usage and format depends on the system parameter being queried or set.

For more information about system-wide parameters, see the parameter. If not otherwise indicated, you must specify '0' for this parameter.

refPvParam  UInt32

A parameter whose usage and format depends on the system parameter being queried or set.

For more information about system-wide parameters, see the parameter. If not otherwise indicated, you must specify for this parameter.

For information on the PVOID datatype, see Windows Data Types.

winIni  SystemParametersWinIniFlags

If a system parameter is being set, specifies whether the user profile is to be updated, and if so, whether the WM_SettingChange message is to be broadcast to all top-level windows to notify them of the change.

This parameter can be '0' if you do not want to update the user profile or broadcast the WM_SettingChange message.
