Scalable Memory Pools
NOTE:
To enable this feature, set the TBB_PREVIEW_MEMORY_POOL macro to 1.
Memory pools allocate and free memory from a specified region or an underlying allocator using thread-safe, scalable operations. The following table summarizes the Memory Pool named requirement. Here, P represents an instance of the memory pool class.
Pseudo-Signature |
Semantics |
---|---|
~P() throw(); |
Destructor. Frees all the allocated memory. |
void P::recycle(); |
Frees all the allocated memory. |
void* P::malloc(size_t n); |
Returns a pointer to n bytes allocated from the memory pool. |
void P::free(void* ptr); |
Frees the memory object specified via ptr pointer. |
void* P::realloc(void* ptr, size_t n); |
Reallocates the memory object pointed by ptr to n bytes. |
Model Types
The memory_pool template class and the fixed_pool class meet the Memory Pool named requirement.
