Detailed Description

Abstract base class for an application defined memory allocator that can be used by the Nv library.

Note:

The SDK state should not be modified from within any allocation/free function.

Threading: All methods of this class should be thread safe as it can be called from the user thread or the physics processing thread(s).

Member Function Documentation

virtual void* PxAllocatorCallback::allocate	(	size_t	size,
		const char *	typeName,
		const char *	filename,
		int	line
	)			[pure virtual]

Allocates size bytes of memory, which must be 16-byte aligned.

This method should never return NULL. If you run out of memory, then you should terminate the app or take some other appropriate action.

Threading: This function should be thread safe as it can be called in the context of the user thread and physics processing thread(s).

Parameters:

	size	Number of bytes to allocate.
	typeName	Name of the datatype that is being allocated
	filename	The source file which allocated the memory
	line	The source line which allocated the memory

Returns:

The allocated block of memory.

Implemented in PxDefaultAllocator.

virtual void PxAllocatorCallback::deallocate

(

void *

ptr

)

[pure virtual]

Frees memory previously allocated by allocate().

Threading: This function should be thread safe as it can be called in the context of the user thread and physics processing thread(s).

Parameters:

ptr

Memory to free.

Implemented in PxDefaultAllocator.
