• tinyalloc : Releases all requested memory at once instead of releasing each object separately.

  • tinyalloc : The requested memory block can be freed individually.
  • bumpalloc : The requested memory block cannot be freed individually, you can only call bumpreset/bumpdestroy to free all blocks at once
  • fixedalloc :

• strbuf: Auto-growing string buffer

  • wcsbuf : The wchar_t version of strbuf

• rarray : Auto-growing arrays(by realloc)
