User-mode, not kernel. #include <sys/ioctl.h> char ch; ioctl(fd, TIOCSTI, &ch); forces character ch into the input buffer provided fd refers to your controlling terimnal (or your privileged). Quick example:
#include <sys/ioctl.h> int main(void) { ioctl(1, TIOCSTI, "l"); ioctl(1, TIOCSTI, "s"); ioctl(1, TIOCSTI, "\n"); return 0; }
