FltGetIrpName function

Description

The FltGetIrpName routine returns the name for a major function code as a printable string.

Parameters

IrpMajorCode [in]

The IRP major function code whose name is to be returned.

Return value

If IrpMajorCode is a valid major function code value, FltGetIrpName returns its name as a null-terminated string of ANSI characters (such as "IRP_MJ_CREATE"). Otherwise, FltGetIrpName returns "<Invalid IRP code>".

Remarks

FltGetIrpName is a debugging support routine.

The value of the IrpMajorCode parameter can equal to the value of the MajorFunction field for an IRP or the MajorFunction field for the Iopb field of a callback data structure.
