ExRaiseDatatypeMisalignment function (ntddk.h)
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.
