Classes

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.
