This is not a good idea unless you KNOW that at least 101 char's have
been allocated for the string.

You might be putting the '\0' in the middle of another string or
variable.

Do you realize that strncpy(dest, src, 100); has the exact same issue? You always have to make sure the destination is big enough. My method isn't any less safe than any of the others.
