GetSystemMetrics / SetSystemMetrics ?

[Andriy Palamarchuk]

Question:
How to update metrics data returned by GetSystemMetrics function?

Problem:
Currently I'm implementing some easiest FIXMEs (e.g. SPI_GETSHOWSOUNDS) 
in function SystemParametersInfo.
GetSystemMetrics is used to return information for a few types of 
SPI_GETxxx actions from this function, including the action I'm working on.
Logic for corresponding SPI_SETxxx actions is not implemented and 
contains commented out calls to SetSystemMetrics. As I understand this 
comment is a mark that corresponding GetSystemMetrics data should be 
updated in this place.

GetSystemMetrics returns data from array sysMetrics. I did not find any 
function which provides update access to the array.

Can you advise how to deal with this problem?
