The other day I was thinking about the function for performing dynamic memory allocation in the C standard library, malloc. From the manual pages, If successful, the malloc() function returns a pointer to allocated memory. If there is an error, it returns a NULL pointer and sets errno to ENOMEM. One of the most common errors when using malloc is not checking for allocation failure. The allocation is not guaranteed to succeed and trying to use a NULL reference can lead to program crashes.
