micro-arena.h
=============

Header only memory allocator in C99 (first fit). It implements
the common memory functions from stdlib.h:

      void *micro_arena_malloc(MicroArena *ma, size_t size);
      void micro_arena_free(MicroArena *ma, void * ptr);
      void *micro_arena_calloc(MicroArena *ma, size_t nmemb, size_t size);
      void *micro_arena_realloc(MicroArena *ma, void * ptr, size_t size);
      void *micro_arena_reallocarray(MicroArena *ma, void * ptr, size_t nmemb, size_t size);

Example
-------


    MicroArena ma;
    micro_arena_init(&ma);

    int array_len = 10;
    int* mem = micro_arena_malloc(&ma, sizeof(int) * array_len);
    assert(mem != NULL);  

    micro_arena_free(&ma, mem);


Usage
-----

Do this:

  #define MICRO_ARENA_IMPLEMENTATION

before you include this file in *one* C or C++ file to create the
implementation.

i.e. it should look like this:

  #include ...
  #include ...
  #include ...
  #define MICRO_ARENA_IMPLEMENTATION
  #include "micro-arena.h"

You can tune the library by #defining certain values. See the
"Config" comments under "Configuration" below.
