c语言键盘调用（国外英文资料） How is the keyboard scan code used in C? This is the value of using bioskey (). When the parameter is 0, the return value of bioskey () is that if the low eight bits are non-zero, the normal key is pressed; If the low eight is zero, the function key is pressed. When the parameter is 1, the test has a button that is pressed, and if the return value is 0, it means that there is no key press, and there is a button press. When the parameter is 2, it means to get the state of the transformation key, which is the transformation key? Transform key including binary and control keys, binary key is num lock, scroll lock, insert and caps lock, control key is left and right shift, CTRL and Alt, the return value of low eight reflects the transformation of key state: 0x01 to the right shift Left-hand shift 0 x04 CTRL key 0 x08 Alt 0x10 scroll lock opens 0x20 num lock opens 0x40 caps lock opens 0x80 insert opens In fact, bioskey directly calls the BIOSs int 16h keyboard I/O interrupt, which is the complete version of int 16h. Keyboard scan size To control the keyboard procedures, often to use some of the key scan code, used to sweep under the first try, every time when trouble really, today again make a small program, use The scan code, just a test program, save all the key scan code in a file, for later use when programming. Here share with you, though Its easy to get it, but at least you can stop everyone from looking up as I did before Scanning key 0x011b ESC 0x3b00 F1 0x3c00 F2 0x3d00 F3 0x3e00 F4 0x3f00 F5 0x4000 F6 0x4100 F7 0x4200 F8 0x4300 F9 0x4400 F10 The main keyboard area: 0x2960 ~ 0x0231 1 0x0332 2 0x0433 3 0x0534 0x0635 0x0736 6 0x0837 7 0x0938 8 0x0a39 9 0x0b30 zero 0x0c2d - 0x0d3d = 0x2b5c 0x0e08 0x0f09 Tab 0x1071 q 0x1177 w 0x1265 e 0x1372 r 0x1474 t 0x1579 y 0x1675 u 0x1769 I 0x186f o 0x1970 p 0x1a5b 0x1b5d) 0x1e61 a 0x1f73 s 0x2064 d 0x2166 f 0x2267 g 0x2368 h 0x246a j 0x256b k 0x266c l 0x273b; 0x2827 0x1c0d returns 0x2c7a z 0x2d78 x 0x2e63 c 0x
