glBuffLock
void glBuffLock(void);
DESCRIPTION
Increments LCD screen locking counter. Graphic calls are recorded in the LCD mem-
ory 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.
