 This is primarily a C programming project.

 == Description ==

 The call `malloc_info()` is useful when looking to heap issues when some
 allocations are not right. I have found this call changes the state of the
 heap. I am not sure what is happening but I think a call like this should
 not effect the state of the heap and only report it.

 The documentation for this call, specification of the requirements, and
 any related documentation around it should be updated when this call
 becomes side-effect free.

 This project could potentially be combined with other projects related to
 memory allocators.
