## Classes
class | btAlignedAllocator< T, Alignment >
| The btAlignedAllocator is a portable class for aligned memory allocations. More...
struct | btAlignedAllocator< T, Alignment >::rebind< O >

## Macros
#define | btAlignedAlloc(size, alignment) btAlignedAllocInternal(size,alignment)
#define | btAlignedFree(ptr) btAlignedFreeInternal(ptr)

## Typedefs
typedef int | size_type
typedef void *( | btAlignedAllocFunc) (size_t size, int alignment)
typedef void( | btAlignedFreeFunc) (void *memblock)
typedef void *( | btAllocFunc) (size_t size)
typedef void( | btFreeFunc) (void *memblock)

## Functions
void * | btAlignedAllocInternal (size_t size, int alignment)
| we probably replace this with our own aligned memory allocator so we replace _aligned_malloc and _aligned_free with our own that is better portable and more predictable More...
void | btAlignedFreeInternal (void *ptr)
void | btAlignedAllocSetCustom (btAllocFunc *allocFunc, btFreeFunc *freeFunc)
| The developer can let all Bullet memory allocations go through a custom memory allocator, using btAlignedAllocSetCustom. More...
void | btAlignedAllocSetCustomAligned (btAlignedAllocFunc *allocFunc, btAlignedFreeFunc *freeFunc)
| If the developer has already an custom aligned allocator, then btAlignedAllocSetCustomAligned can be used. The default aligned allocator pre-allocates extra memory using the non-aligned allocator, and instruments it. More...

## Function Documentation

void* btAlignedAllocInternal | ( | size_t | size,
|  | int | alignment
| ) |  |

we probably replace this with our own aligned memory allocator so we replace _aligned_malloc and _aligned_free with our own that is better portable and more predictable

Definition at line 159 of file btAlignedAllocator.cpp.

void btAlignedAllocSetCustom | ( | btAllocFunc * | allocFunc,
|  | btFreeFunc * | freeFunc
| ) |  |

The developer can let all Bullet memory allocations go through a custom memory allocator, using btAlignedAllocSetCustom.

Definition at line 101 of file btAlignedAllocator.cpp.

void btAlignedAllocSetCustomAligned | ( | btAlignedAllocFunc * | allocFunc,
|  | btAlignedFreeFunc * | freeFunc
| ) |  |

If the developer has already an custom aligned allocator, then btAlignedAllocSetCustomAligned can be used. The default aligned allocator pre-allocates extra memory using the non-aligned allocator, and instruments it.

void btAlignedFreeInternal | ( | void * | ptr | ) |
