View source for WM MOUSEMAP

This message is specific to version 2.1, or higher, of the OS/2 operating system.

This message is used only by applications that wish to remap mouse messages in the PM input queue. It is not recommended for general application usage, and applications should NOT process this message in their window procedures.

==Syntax==
<pre>
param1
    ULONG ulPhysButton;   /* The physical button number (1, 2, or 3). */

param2
    ULONG ulMappedButton; /* The button to be mapped to (1, 2, or 3). */
</pre>

==Parameters==
;''ulPhysButton'' (ULONG) - input: The physical button number (1, 2, or 3).
;''ulMappedButton'' (ULONG) - input: The button to be mapped to (1, 2, or 3).
;''ulReserved'' (ULONG) - input: Reserved value, should be 0.

==Returns==
;''ulReserved'' (ULONG) - returns: Reserved value, should be 0.

==Remarks==
PM will interpret this message when it is read from the PM input queue, as a request to remap all subsequent mouse events for the desired button, until another WM_MOUSEMAP message is received, cancelling that remap request. This message has no meaning to an application.

==Default Processing==
The default window procedure takes no action on this message, other than to set ''ulReserved'' to 0.
