Function documentation

void* FixedPoolAllocator::Alloc(size_t size, const char* name, unsigned int flags) virtual

Parameters
size size of the requested block.
name name of the block (normally used for debugging purposes)
flags additional information on how to allocate the block (MEM_PERM or MEM_TEMP)
Returns A pointer to the allocated block if successful. NULL if the block could not be allocated.

void* FixedPoolAllocator::Alloc(size_t size, const char* name, unsigned int flags, unsigned int align, unsigned int alignOffset = 0) virtual

Parameters
size size of the requested block.
name name of the block (normally used for debugging purposes)
flags additional information on how to allocate the block (MEM_PERM or MEM_TEMP)
align some power-of-2 boundary the block must be allocated on. address returned is guaranteed to be aligned to the requested boundary.
alignOffset a "header" amount which is subtracted from the power-of-2 alignment. A location inside a memory block will be aligned to this boundary.
Returns A pointer to the allocated block if successful. NULL if the block could not be allocated.

void FixedPoolAllocator::Free(void* block, size_t size = 0) virtual

Parameters
block pointer to the block to be freed.
size optional. It may be used to find the pool that the block belongs to. The implementation is free to ignore this and the caller cannot assume that the implementation will do anything with it.
