With the caveat that I haven't done any serious programming in C for
many years:  As I recall, I always used a protocol halfway between
these, as:

char *func(size_t bufsiz)
{
        char *retval = malloc (bufsiz);
        if (retval == NULL) return (NULL);
        /* whatever */
        return (retval);
}


It looks like this would lead to memory leaks that would be difficult
to track down along a wide variety of code paths upon return.

I recommend the first style: int func(char *buf, size_t bufsize).  All
malloc and frees are then encouraged to sandwich this call.
