FLT_IS_REISSUED_IO macro (fltkernel.h)

Article
02/22/2024

The FLT_IS_REISSUED_IO macro determines whether the given callback data structure represents a reissued I/O operation.

Syntax

void FLT_IS_REISSUED_IO(
   Data
);

Parameters

Data

[in] Pointer to the callback data (FLT_CALLBACK_DATA) structure for an I/O operation.

Return value

None

Remarks

FLT_IS_REISSUED_IO returns TRUE if the reissued I/O operation flag is set in the callback data structure; FALSE otherwise.

The FLT_IS_REISSUED_IO macro checks whether the FLTFL_CALLBACK_DATA_REISSUED_IO flag is set in the Flags member of the FLT_CALLBACK_DATA structure that the Data parameter points to. This flag is set by FltReissueSynchronousIo when an I/O operation is reissued. This flag is valid only for IRP-based I/O operations. To determine whether an I/O operation is IRP-based, use the FLT_IS_IRP_OPERATION macro.
