; Final touches after verification of whole codebase.
GTWVG still needs changes.

|
* $CATEGORY$
|
|
* Keyboard/Mouse
|
|
* $ONELINER$
|
|
* Enable or disable the Print Screen key
|
|
* $SYNTAX$
|
|
* FT_PRTSCR( [ <lSetStat> ] ) -> lCurStat
|
|
* $ARGUMENTS$
|
|
* <lSetStat> set to .T. will enable the Print Screen key,
|
|
* .F. will disable it. If omitted, leaves status as is.
|
|
* $RETURNS$
|
|
* The current state: .T. if enabled, .F. if disabled.
|
|
* $DESCRIPTION$
|
|
* This function is valuable if you have a need to disable the
|
|
* printscreen key. It works by fooling the BIOS into thinking that
|
|
* a printscreen is already in progress. The BIOS will then refuse
|
|
* to invoke the printscreen handler.
|
|
* $EXAMPLES$
|
|
* FT_PRTSCR( .F. ) && Disable the printscreen key
|
|
* FT_PRTSCR( .T. ) && Enable the printscreen key
|
|
* MemVar := FT_PRTSCR() && Get the current status
|
|
* $SEEALSO$
|
|
* FT_CAPLOCK() FT_CTRL() FT_NUMLOCK() FT_SHIFT() FT_ALT()
