TINYHEAP

Simple, linked-list implementation of a heap in pure C.

See the tinyheap_config.h in the default/ folder for buildtime configurations.

To be used in an embedded environment with small ram.

Use the heap by doing something like this:

  #include "tinyheap.h"
  
  // use this space as heap
  static char heap_space[4096];
  // this is the heap metainfo
  static tinyheap heap;
  
  // initiate heap, do this at startup
  void startup_heap_init(void) {
    th_init(&heap, heap_space, sizeof(heap_space));
  }
  
  // use the heap
  void use_heap(void) {
    void *data = th_malloc(&heap, 100);
    if (data == 0) {
      .. out of memory ..
    } else {
      .. do something with those hundred bytes ..
      th_free(&heap, data);
    }
  }
