to allocate space for the pathnames of each file. You have your pointer point
to the local array declared in your function, which will be invalid once you
leave the function. Thus a working version would look like:
ptr->path = strcpy (calloc (sizeof (char), strlen (path_name) + 1),
ptr->size = statbuf.st_size;
ptr->next = NULL;
This explicitely allocates enough dynamic memory to fill in the string (plusQuote:}
the terminating \0) and then copies the string into it.
Same applies if you wanted to free the list. You'd have to free those pathname
strings first and then the list item itself.
