The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
simulate_ukeypress – Stuffs an unicode key into the keyboard buffer. Allegro game programming library. Synopsis #include <allegro.h> void simulate_ukeypress(int key, int scancode); Description Stuffs a key into the keyboard buffer, just as if the user had pressed it.
