Memory Allocation in C

A program was written by my friend and fellow software engineer Thomas to demonstrate how to use memory allocation using C programming language. Thank you Tom for sharing your code to us.

Program Listing

#define DEBUG

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <assert.h>

void* alloc_mem(size_t size, const char *file, unsigned line)
{
     assert(size > 0);
     assert(file != NULL);

     void* res = malloc(size);
     if (res == NULL)
         fprintf(stderr, "malloc failed at %s(%u)\n",file, line);
     else {
         fprintf(stderr, "alloc\t%u\t%u\t%s\t%u\n", (unsigned int)res,
size,file, line);
         memset(res, 0xCC, size);
     }

     return res;
}

void free_mem(void *p, const char *file, unsigned line)
{
     assert(p != NULL);
     fprintf(stderr, "free\t%u\t?\t%s\t%u\n", (unsigned int)p, file, line);
}

#ifdef DEBUG
#define malloc(size)    alloc_mem(size, __FILE__, __LINE__)
#define free(p)         free_mem(p, __FILE__, __LINE__);
#endif

int f()
{
     int *num = malloc(sizeof(int *));

     return *num;
}

int main()
{
     int *ip = malloc(sizeof(int *));
     if (ip != NULL)
     {
         *ip = 11;
         printf("*ip = %d\n", *ip);
     }
     printf("Num = %d\n", f());
     free(ip);
     //system("pause");
     return EXIT_SUCCESS;
