- hkbd (HKBD) - input

Return Code
rc (APIRET) - returns
KbdPeek returns one of the following values:
- 0 NO_ERROR
- 375 ERROR_KDB_INVALID_IOWAIT
- 439 ERROR_KBD_INVALID_HANDLE
- 445 ERROR_KBD_FOCUS_REQUIRED
- 447 ERROR_KBD_KEYBOARD_BUSY
- 504 ERROR_KBD_EXTENDED_SG
Remarks
Note: KbdPeek returns a complete keystroke. This behavior is unlike the OS/2 1.3 version, which returned only a single byte. This is significant only for DBCS characters.
If bit 0 of fbStatus is set, the character returned is either 0 or 0xe0. The Unicode character contains the virtual key.
For valid characters, the character in the current code page is returned, and the Unicode character contains the Unicode encoding of the character.
