Memory allocations of less than PAGE_SIZE are not necessarily page-aligned but are aligned to 8-byte boundaries in 32-bit systems and to 16-byte boundaries in 64-bit systems.Ī successful allocation requesting NumberOfBytes PAGE_SIZE succeeds and NumberOfBytes is not an exact multiple of PAGE_SIZE, the last page in the allocation contains bytes that are not part of the caller's allocation. Memory allocations of PAGE_SIZE or less are allocated within a page and do not cross page boundaries. If NumberOfBytes is PAGE_SIZE or greater, a page-aligned buffer is allocated. This routine is used for the general pool allocation of memory. Otherwise, the routine returns a pointer to the allocated memory.

returnsĮxAllocatePoolWithTag returns NULL if there is insufficient memory in the free pool to satisfy the request.

Each allocation code path should use a unique pool tag to help debuggers and verifiers identify the code path. Each ASCII character in the tag must be a value in the range 0x20 (space) to 0x7E (tilde). The string is usually specified in reverse order (for example, '1gaT'). Specify the pool tag as a non-zero character literal of one to to four characters delimited by single quotation marks (for example, 'Tag1'). The pool tag to use for the allocated memory.

The POOL_COLD_ALLOCATION flag is only advisory and is supported starting with Windows XP. To reduce the amount of resident pool memory as much as possible, you should not reference these allocations frequently. Similarly, you can modify the PoolType value by bitwise-ORing this value with the POOL_COLD_ALLOCATION flag as a hint to the kernel to allocate the memory from pages that are likely to be paged out quickly. Use of the POOL_RAISE_IF_ALLOCATION_FAILURE flag is not recommended because it is costly. This flag causes an exception to be raised if the request cannot be satisfied.

You can modify the PoolType value by bitwise-ORing this value with the POOL_RAISE_IF_ALLOCATION_FAILURE flag. For a description of the available pool memory types, see POOL_TYPE. For more information, see Updating deprecated ExAllocatePool calls to ExAllocatePool2 and ExAllocatePool3.

The ExAllocatePoolWithTag routine allocates pool memory of the specified type and returns a pointer to the allocated block.ĮxAllocatePoolWithTag has been deprecated in Windows 10, version 2004 and has been replaced by ExAllocatePool2.
