+ | ==Description== | ||
+ | This call clears the keystroke buffer. | ||
+ | |||
+ | ==Syntax== | ||
+ | | ||
+ | |||
+ | ==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== | ||
