◆ MEM_use_guarded_allocator()

void MEM_use_guarded_allocator ( void )

Switch allocator to slow fully guarded mode.

Use for debug purposes. This allocator contains lock section around every allocator call, which makes it slow. What is gained with this is the ability to have list of allocated blocks (in an addition to the tracking of number of allocations and amount of allocated bytes).

Note: The switch between allocator types can only happen before any allocation did happen.

◆ MEM_use_lockfree_allocator()

void MEM_use_lockfree_allocator ( void )

Switch allocator to fast mode, with less tracking.

Use in the production code where performance is the priority, and exact details about allocation is not. This allocator keeps track of number of allocation and amount of allocated bytes, but it does not track of names of allocated blocks.

Note: The switch between allocator types can only happen before any allocation did happen.
