simulate_keypress - Stuffs a key into the keyboard buffer. Allegro game programming library. SYNOPSIS
#include <allegro.h> void simulate_keypress(int key); DESCRIPTION
Stuffs a key into the keyboard buffer, just as if the user had pressed it. The parameter is in the same format returned by readkey(). Exam- ple: simulate_keypress(KEY_SPACE << 8); if (readkey() == (KEY_SPACE << 8)) allegro_message("You simulated Alt+Space "); SEE ALSO

NAME
readkey - Returns the next character from the keyboard buffer. Allegro game programming library. SYNOPSIS
#include <allegro.h> int readkey(); DESCRIPTION
Returns the next character from the keyboard buffer, in ASCII format. If the buffer is empty, it waits until a key is pressed. You can see if there are queued keypresses with keypressed(). The low byte of the return value contains the ASCII code of the key, and the high byte the scancode. The scancode remains the same whatever the state of the shift, ctrl and alt keys, while the ASCII code is affected by shift and ctrl in the normal way (shift changes case, ctrl+letter gives the position of that letter in the alphabet, eg. ctrl+A = 1, ctrl+B = 2, etc). Pressing alt+key returns only the scan- code, with a zero ASCII code in the low byte. For example: int val; ... val = readkey(); if ((val & 0xff) == 'd') /* by ASCII code */ allegro_message("You pressed 'd' "); if ((val >> 8) == KEY_SPACE) /* by scancode */ allegro_message("You pressed Space "); if ((val & 0xff) == 3) /* ctrl+letter */ allegro_message("You pressed Control+C "); if (val == (KEY_X << 8)) /* alt+letter */ allegro_message("You pressed Alt+X "); This function cannot return character values greater than 255. If you need to read Unicode input, use ureadkey() instead. SEE ALSO
