This routine is a wrapper and replacement option for ExAllocatePoolWithTag.
To support Windows versions earlier than Windows 10, version 2004, use ExAllocatePoolUninitialized or ExAllocatePoolZero.
To support Windows 10, version 2004 and later, use ExAllocatePool2.
PoolTypeDefines the POOL_TYPE parameter PoolType.
NumberOfBytesDefines the SIZE_T parameter NumberOfBytes.
TagDefines the ULONG parameter Tag.
Use this wrapper if you want to explicitly not zero the allocated memory range.
A driver should only access memory within the byte range that it allocates. Accessing memory outside this range may corrupt the pool and cause the system to crash.
Memory that ExAllocatePoolUninitialized allocates is uninitialized. A kernel-mode driver must first zero this memory if it is going to make it visible to user-mode software (to avoid leaking potentially privileged contents).
See the Remarks section of ExAllocatePoolWithTag for additional guidance.
