As a side note, I'd generally stay away from strcpy() and strcat().
It is estimated that about 80% of all security vulnerabilities are
buffer overflows.
If your OS supports it, use strlcpy() and strlcat() [OBSD 2.4+, FBSD 3.3+,
Solaris 8+, dunno about others].
Else, use at least strncpy() and strncat(), and make sure the result is
null-terminated.
To paraphrase Dave N., there really is no excuse for writing vulnerable code.
