MmUnlockPages function

Description

The MmUnlockPages routine unlocks the physical pages that are described by the specified memory descriptor list (MDL).

Parameters

MemoryDescriptorList [in, out]

A pointer to an MDL.

Remarks

The memory described by the specified MDL must have been locked previously by a call to MmProbeAndLockPages. If the specified MDL is mapped to system address space, MmUnlockPages releases this mapping before it unlocks the pages.

For more information, see Using MDLs.
