RtlStoreUlongPtr macro (wdm.h)

The RtlStoreUlongPtr macro stores a specified ULONG_PTR value at a specified memory location, avoiding memory alignment faults.

Syntax

void RtlStoreUlongPtr(
 [out] ADDRESS,
 [in] VALUE
);

Parameters

[out] ADDRESS

A pointer to a location in which to store the ULONG_PTR value.

[in] VALUE

Specifies the ULONG_PTR value to be stored.

Return value

None

Remarks

RtlStoreUlongPtr avoids memory alignment faults. If the value of Address is not aligned to the storage requirements of a ULONG_PTR, RtlStoreUlongPtr stores the bytes of Value beginning at the memory location (PUCHAR)Address.

RtlStoreUlongPtr runs at any IRQL if Address points to nonpaged pool; otherwise it must run at IRQL <= APC_LEVEL.
