.TH keyboard_clearstate 3 "29 July 1997" "Svgalib (>= 1.2.11)" "Svgalib User Manual"
|
|
.SH NAME
|
|
keyboard_clearstate \- reset the state of all keys when in raw keyboard mode
|
|
.SH SYNOPSIS
|
|
|
|
.B "#include <vgakeyboard.h>"
|
|
|
|
.BI "void keyboard_clearstate(void);"
|
|
|
|
.SH DESCRIPTION
|
|
When in raw keyboard mode, svgalib receives press and release events from the kernel and
|
|
keeps track which keys are currently pressed. Calling
|
|
.B keyboard_clearstate()
|
|
sets this information to all keys released. You can use this for cleanup at certain places
|
|
in your program. In addition svgalib resets the states of all keys when a VC switch occurs
|
|
because it does not know the current state of keys when it regains control of the console.
