GNU C library's (glibc's) malloc library implementation

void  *malloc(size_t size);

void  free(void *ptr);

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

void  *calloc(size_t nelem, size_t size);

void  show_alloc_mem();

void  show_free_mem();

Injection

The project comes with an injector (LD_PRELOAD hooking)

• Running a binary using the inject script will make the program use my malloc library instead of the glibc's one

./inject [BINARY]

Make

Given Makefile contains all standard rules

• all
• clean
• fclean
• re
