EZmem

V3 of wraloc - a memory debug tool to help understand your program and help find leaks

Usage

curl -O https://raw.githubusercontent.com/lorenuars19/EZmem/main/ezmem.h

then

#include "ezmem.h"

What is this, what does it do

This project wraps calls to malloc and free using #define, hence it can't wrap calls that are outside of your own code.
It creates an .ezmem folder where the program is executed.
Also this tool makes calls to signal function to call create_mem_report on SIGINT, SIGTERM, SIGABRT, SIGBUS, SIGQUIT. Also this tool never allocates memory during execution, everything is done with static buffers.

Content of .ezmem folder

• README : this short explanation
• .ids.memid : internal file to track current ID whitout the use of global variable
• log.memlog : Log of all the calls to malloc and free
• mem/ : contains the memory blocks
• leaks/ : contains the memory blocks that have never been freed; A leaked block also contains a memory dump to help you find the source of your leak

At the end of execution a report.memreport is generated to summarize the last recorded memory state.

More info

This repo contains header fragments in the srcs/ folder which are concatenated to the final ezmem.h, this is done only for ease of developement.
You only need to get the latest ezmem.h and include it in the files you want to be tracked.
This tool uses open and close to write and read to files, however it WILL not use more more than one FD.
The calls to open and I/O manip are all encapsulated inside the wrapped funcs, so it WILL not affect your FDs.
