pointer dmxCommonCopyPrivate ( DeviceIntPtr pDevice )

-

Returns a pointer to the private area for the device that comes just prior to pDevice in the current dmxInput device list. This is used as the private area for the current device in some situations (e.g., when a keyboard and mouse form a pair that should share the same private area). If the requested private area cannot be located, then NULL is returned.

void dmxCommonSaveState ( pointer private )

-

This routine saves and resets some important state for the backend and console device drivers:

-

the modifier map is saved and set to 0 (so DMX controls the LEDs)
the key click, bell, led, and repeat masks are saved and set to the values that DMX claims to be using

-

This routine and dmxCommonRestoreState are used when the pointer enters and leaves the console window, or when the backend window is active or not active (for a full-screen window, this only happens at server startup and server shutdown).

Given the global coordinates x and y, determine the screen with the lowest number on which those coordinates lie. If they are not on any screen, return -1. The number returned is an index into dmxScreenInfo and is between -1 and dmxNumScreens - 1, inclusive.
