The <service> argument can be any of the following manifest constants: _KEYBRD_READ _NKEYBRD_READ _KEYBRD_READY _NKEYBRD_READY _KEYBRD_SHIFTSTATUS _NKEYBRD_SHIFTSTATUS Return Value With the ...READ and ...SHIFTSTATUS arguments, the _bios_keybrd function returns the contents of the AX register after the BIOS call. With the ...READY argument, _bios_keybrd returns 0 if there is no key. If there is a key, _bios_keybrd returns the key waiting to be read (that is, the same value as _KEYBRD_READ). With the ...READ and ...READY arguments, the _bios_keybrd function returns -1 if CTRL+BREAK has been pressed and is the next keystroke to be read. -♦-
