.SH DESCRIPTION
|
||
|
|
queries the number of axes (number of continuous ranges which the joystick allows to choose
|
||
|
|
from) and buttons. The old version 0.* joystick protocol reports 2 axes (x and y) and 4 buttons
|
||
|
|
although the actual joystick will usually have less (often two) buttons.
|
||
|
|
|
||
|
|
svgalib supports up to 127 axes and buttons, provided the underlying device driver does it.
|
||
|
|
|
||
|
|
.SH CAVEATS
|
||
|
|
This function is only available in ELF versions of svgalib. Due to backwards
|
||
|
|
compatibility issues it cannot be used with shared a.out libs.
