|
.SH SYNOPSIS
|
||
|
|
|
||
|
|
.B "#include <vgakeyboard.h>"

|
||
|
|
.SH DESCRIPTION
|
||
|
|
These routines check the keyboard buffer for any raw keyboard events and do the
|
||
|
|
necessary updates to the internal buffers of
|
||
|
|
.BR keyboard_clearstate (3)
|
||
|
|
and
|
||
|
|
.BR keyboard_keypressed (3).
|
||
|
|
|
||
|
|
When there are no such events,
|
||
|
|
.B keyboard_update()
|
||
|
|
returns 0 immediately (non-zero else) whereas
|
||
|
|
.B keyboard_waitforupdate()
|
||
|
|
blocks and waits until an event occurs.
|
||
|
|
|
||
|
|
.BR vga_waitevent (3)
|
||
|
|
allows to wait for keyboard and other events at the same time.
