| void kbdLinuxBell |
( |
DevicePtr |
pDev, |

int |
percent, |
|
|
int |
volume, |
|
|
int |
pitch, |
|
|
int |

) |
|
|
|
|
Ring the bell.
Note: we completely ignore the volume, since Linux's ioctl() interface does not provide a way to control it. If it did, the XBell manpage tells how the actual volume is a function of the percent and the (base) volume.
Note that most of the other PC-based bell drivers compute the duration for KDMKTONE as a function of the volume and the duration. For some drivers, the duration is only measured in mS if the volume is 50, and is scaled by the volume for other values. This seems confusing and possibly incorrect (the xset man page says that the bell will be "as closely as it can to the user's specifications" -- if we ignore the volume and set the duration correctly, then we'll get one parameter "wrong" -- but if we use the volume to scale the duration, then we'll get both parameters "wrong"). |
