The FltIsIoCanceled routine checks if an IRP-based operation has been canceled.
Syntax
BOOLEAN FLTAPI FltIsIoCanceled(
[in] PFLT_CALLBACK_DATA CallbackData
);
Parameters
[in] CallbackData
Pointer to the callback data structure for the operation (FLT_CALLBACK_DATA).
Return value
FltIsIoCanceled returns TRUE if an IRP-based operation has been canceled and FALSE if the operation has not been canceled or if it is not an IRP-based operation.
Remarks
It is a programming error to call FltIsIoCanceled for an operation that is not IRP-based. To determine whether the operation is IRP-based, use the FLT_IS_IRP_OPERATION macro.
