NO LEAKS NO REEKS

Memory Management Library

This library provides a simple mechanism to manage dynamic memory allocations in C and to ensure that all allocated memory is freed at the end of the program, preventing memory leaks. It includes functions for allocating and freeing memory, and maintains a list of all allocated addresses.

Functions

void *ft_alloc(size_t size, void *ptr, char mode)

Allocates, reallocates, or frees memory based on the specified operation.

• Parameters:

  • size: The size of the memory to allocate.
  • ptr: The pointer to the memory to reallocate or free. Set to NULL for new allocations.
  • mode: The operation to perform. This can be:
    • MALLOC for malloc
    • CALLOC for calloc
    • FREE_PTR to free a specific pointer
    • FREE_ALL to free all allocated memory

• Returns: A pointer to the allocated memory, or NULL if an error occurs.

instalation

• clone the repo inside your main project:

  git clone git@github.com:nourddine-benyahya/ft_alloc.git
  

• append this inside your makefile in building target rule

  make -C ft_alloc all
  

• append this inside your makefile in librarys includes

  alloc/ft_alloc.a
  

• include #include "ft_alloc.h" in your header file

  #include "ft_alloc.h"
  

example :

before :

    LIBS = libft/libft.a
    $(NAME) : $(OBJ)
          $(CC) $(CFLAGS) $(OBJ) $(LIBS) -o $(NAME)

after :

    LIBS = libft/libft.a alloc/ft_alloc.a
    $(NAME) : $(OBJ)
          make -C ft_alloc all
          $(CC) $(CFLAGS) $(OBJ) $(LIBS) -o $(NAME)

make the libarary cd ft_alloc

Usage

simple testing Code Example

#include "ft_alloc.h"

void leaks(void)
{
    system("leaks a.out");
}

int ft_testing(void)
{
    //check memory leaks at the exit of the programm
    atexit(leaks);

    // Allocate memory using malloc
    void *ptr1 = ft_alloc(sizeof(char *), NULL, MALLOC);

    // Allocate memory using calloc
    void *ptr2 = ft_alloc(sizeof(int *), NULL, CALLOC);

    // Free a specific pointer
    ft_alloc(0, ptr1, FREE_PTR);

    // Free all allocated memory
    ft_alloc(0, NULL, FREE_ALL);

    return (0);
}
int main()
{
    ft_testing();
}
