XALLOC_ALLOCATOR_IDS Enumeration

Defines the range for the set of IDs for different types of allocators used by memory allocation routines.

Syntax

typedef enum _XALLOC_ALLOCATOR_IDS
{
    eXALLOCAllocatorId_GameMin = 0,
    eXALLOCAllocatorId_GameMax = 127,
    eXALLOCAllocatorId_PlatformReservedMin = 128,
    eXALLOCAllocatorId_D3D = 128,
    eXALLOCAllocatorId_Audio = 129,
    eXALLOCAllocatorId_PlatformReservedMax = 191,
    eXALLOCAllocatorId_MiddlewareReservedMin = 192,
    eXALLOCAllocatorId_MiddlewareReservedMax = 255
} XALLOC_ALLOCATOR_IDS;

Constants

Constant	Description
eXALLOCAllocatorId_GameMin	Start of the range of allocator IDs available to titles for allocation.
eXALLOCAllocatorId_GameMax	End of the range of allocator IDs available to titles for allocation.
eXALLOCAllocatorId_PlatformReservedMin	Start of the range of allocator IDs used by the system.
eXALLOCAllocatorId_D3D	Allocator ID for Direct 3D.
eXALLOCAllocatorId_Audio	Allocator ID for audio.
eXALLOCAllocatorId_PlatformReservedMax	End of the range of allocator IDs used by the system.
eXALLOCAllocatorId_MiddlewareReservedMin	Start of the range of allocator IDs reserved for middleware.
eXALLOCAllocatorId_MiddlewareReservedMax	End of the range of allocator IDs reserved for middleware.

Remarks

Each allocation is associated with an allocator ID, which identifies the subsystem which is requesting the allocation (or free). There are three potential sources of allocations; Title, Platform and Middleware components.

Title developers should feel free to use any of the values in the range eXALLOCAllocatorId_GameMin to eXALLOCAllocatorId_GameMax to identify which of their subsystems are performing allocations.

If you are a middleware vendor and would like to reserve an allocator ID, please contact your developer account manager.
