Typedef Documentation
◆ dart_allocator_t
| typedef struct dart_allocator_struct* dart_allocator_t |
DART allocator used for non-collective global memory allocations using dart_allocator_alloc similar to dart_memalloc.
An instance of the allocator has to be created using dart_allocator_new before allocating memory using dart_allocator_alloc, which can then be shared with other units in the same team. The memory has to be free'd using dart_allocator_free by the unit that allocated it. The allocator should be destroyed after all allocations have been free'd using dart_allocator_destroy.
