Memory Management

To allocate and deallocate memory blocks, the ANSI library provides the following functions:

  void* malloc(size_t size);
  
  

  void* calloc(size_t n, size_t size);

  

  void* realloc(void* ptr, size_t size);

  

  void free(void* ptr);

  

Because it is not possible to implement these functions in a way that suits all possible target processors and memory configurations, all these functions are based on the system module heap.c file, which can be modified by the user to fit a particular memory layout.
