Sets typematic rate.
int ioctl (FileDescriptor, KSTRATE, Arg) int FileDescriptor; uint *Arg;
The KSTRATE ioctl subroutine call changes the rate at which a pressed key repeats itself, specified in number of repeats per second. The minimum rate is 2 repeats per second, and the maximum rate is 30 repeats per second.
When keyboard diagnostics are enabled, the KSTRATE ioctl subroutine call fails and sets the errno global variable to a value of EBUSY.
|FileDescriptor||Specifies the open file descriptor for the keyboard.|
|Arg||Specifies the address of an integer that contains the desired typematic rate.|
This ioctl subroutine call is part of Base Operating System (BOS) Runtime.
