ptmalloc2v

ptmalloc2v is a tool for those who like to use printf function to debug their code.
This little library is really simple to use and just print some heap info.

Installation

git clone https://github.com/theoricien/ptmalloc2v
sudo make install && make

Your .a file will be in libs/ directory.

Usage

You can refer to doc/ directory, there is some useful explainations about the library
The principle is simple, there are 3 functions: heap_init, heap_view and heap_end:
heap_init needs to be call before any use of the heap
heap_view can be used undefinitely to print heap content you want
heap_end is optional, but free the ptm2v_info structure properly

Example

#include <stdio.h>
#include <stdlib.h>
#include "libptm2v.h"

int
main (int   argc,
      char  * argv [])
{
    // Init stuff
    struct ptm2v_info * tmp = heap_init();

    // code
    heap_view(tmp, DEFAULT_FLAGS, NULL, 0, NULL, 0, stdout);
    // code

    // End/free stuff
    heap_end(&tmp);

    return EXIT_SUCCESS;
}
