ExRaiseDatatypeMisalignment function (ntddk.h)

  • Article

The ExRaiseDatatypeMisalignment routine can be used with structured exception handling to throw a driver-determined exception for a misaligned data type that occurs when a driver processes I/O requests.

Syntax

void ExRaiseDatatypeMisalignment();

Return value

None

Remarks

ExRaiseDatatypeMisalignment raises an exception with the exception code set to STATUS_DATATYPE_MISALIGNMENT.

Because ExRaiseDatatypeMisalignment can only be used at IRQL = PASSIVE_LEVEL, only high-level drivers typically use this routine — for example, file system drivers.
