Wow!  I'm impressed.  Thank you!

Oh, I hope there's an answer section in the back
of the book.

Proving my ignorance once again ...

0v~/eg/c>cat malmalloc.c
main ()
{
    char *buf, *to, *src = "hello world";
    int size = 8, newsize;

    newsize = strlen (src) + 1;
    buf = (char *) malloc (size);
    to = buf;

    if (newsize > size)
        buf = (char *)realloc (buf, newsize);
    while (newsize--)
        *to++ = *src++;

    printf ("%s\n", buf);
}
0v~/eg/c>./malmalloc.exe 
hello world
12v~/eg/c>



(assumes newsize is initialized).
