User’s Manual

Increments LCD screen locking counter. Graphic calls are recorded in the LCD memory buffer and are
not transferred to the LCD if the counter is non-zero.
NOTE: glBuffLock() and glBuffUnlock() can be nested up to a level of 255, but be
sure to balance the calls. It is not a requirement to use these procedures, but a set of
glBuffLock()
and glBuffUnlock() bracketing a set of related graphic calls speeds
up the rendering significantly.
RETURN VALUE
None.
SEE ALSO
glBuffUnlock, glSwap
Decrements the LCD screen locking counter. The contents of the LCD buffer are transferred to the LCD
if the counter goes to zero.
RETURN VALUE
None.
SEE ALSO
glBuffLock, glSwap
Checks the LCD screen locking counter. The contents of the LCD buffer are transferred to the LCD if the
counter is zero.
RETURN VALUE
None.
SEE ALSO
glBuffUnlock, glBuffLock, _glSwapData
(located in the library specifically for the LCD
that you are using)
Sets the drawing method (or color) of pixels drawn by subsequent graphic calls.
PARAMETER
type
value can be one of the following macros.
PIXBLACK
draws black pixels (turns pixel on).
PIXWHITE
draws white pixels (turns pixel off).
PIXXOR
draws old pixel XOR'ed with the new pixel.
RETURN VALUE
None.
