Description

This call clears the keystroke buffer.

Syntax

KbdFlushBuffer (KbdHandle)

Parameters

; KbdHandle (HKBD) - input : Default keyboard or the logical keyboard.

Return Code

rc (USHORT) - return

Return code descriptions are: * 0 NO_ERROR * 439 ERROR_KBD_INVALID_HANDLE * 445 ERROR_KBD_FOCUS_REQUIRED * 447 ERROR_KBD_KEYBOARD_BUSY * 464 ERROR_KBD_DETACHED * 504 ERROR_KBD_EXTENDED_SG

Remarks

KbdFlushBuffer completes when the handle has access to the physical keyboard (focus), or is equal to zero and no other handle has the focus.

Family API Considerations

Some options operate differently in the DOS mode than in the OS/2 mode. The KbdHandle is ignored when coding in the DOS mode.

Example Code
