Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

USHORT DosDevIOCtl(0L, pfHotKey, 0x0055, 0x0007, hDevice)

The MOU_SETHOTKEYBUTTON function sets the mouse-button equivalent for the
system hot key.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pfHotKey   Points to the variable that specifies the hot key. This variable
           can be a combination of the following values:
 
           Value          Meaning
           ─────────────────────────────────────────────────────────────────
           MHK_NO_HOTKEY  No system hot key used.
 
           MHK_BUTTON1    Button 1 is system hot key.
 
           MHK_BUTTON2    Button 2 is system hot key.
 
           MHK_BUTTON3    Button 3 is system hot key.
 
           If 0x0001 is specified, no system hot-key support is provided. If
           multiple values are given (excluding 0x0001), the system hot key
           requires that the indicated buttons be pressed simultaneously.
 
hDevice    Identifies the pointing device that receives the device-control
           function. The handle must have been created previously by using
           the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
 
Comments
 
This function can be called only by the process that initially issues it and
should be used only by the command shell.
