To get more control of the memory management one can create custom allocators. There are many ways of setting up a custom allocator depending on the needs of the program.

Allocator Types
  • Region: Allocate memory with an id, release id release all allocated mem.
  • Static Allocator that gets memory from a specifc address.
  • Memory pool
  • Slab: Splits assigned memory into slabs and each slab into slots. Return slots that fit requested memory.
Common allocator functions
Trace allocations. Like mem usage, number, size.

Common allocator options:
  • Align:        Make sure that allocated memory is aligned to a specific byte size.
  • Canary        Add buffer at and before allocations to check for buffer overuns.
  • Zero:        Sets allocated memory to 0.
