◆ _IRQL_requires_max_() [1/2]

_IRQL_requires_max_ ( APC_LEVEL  )

Probes and locks virtual pages in memory for the specified process.

Parameters
[in,out]MemoryDescriptorListMemory Descriptor List (MDL) containing the buffer to be probed and locked.
[in]ProcessThe process for which the buffer should be probed and locked.
[in]AccessModeAccess mode for probing the pages. Can be KernelMode or UserMode.
[in]LockOperationThe type of the probing and locking operation. Can be IoReadAccess, IoWriteAccess or IoModifyAccess.
Returns
Nothing.

MmProbeAndLockPages
Remarks
Must be called at IRQL <= APC_LEVEL

Probes and locks virtual pages in memory for the specified process.

Frees previously reserved amount of memory in system virtual address space.

Parameters
[in]NumberOfBytesSize, in bytes, of memory to reserve.
[in]PoolTagPool Tag identifying the buffer. Usually consists from 4 characters in reversed order.
Returns
A pointer to the 1st memory block of the reserved buffer in case of success, NULL otherwise.
Remarks
Must be called at IRQL <= APC_LEVEL
Parameters
[in]BaseAddressA pointer to the 1st memory block of the reserved buffer.
