It is possible to get a name of a file associated with a loop device
without root's privileges.
The path of the backing file of loop device "/dev/loop0" for
example,can be obtained by reading:
A few comments about your code:
1. No need to cast return value of malloc() as the language will
automatically do it for you.
2. Its perfectly fine to free a NULL pointer and hence no need to
check if a variable is not NULL
before passing it to free()
