Keeping in mind, of course, that memset() may not be present on a POSIX system that provides common-usage C language-dependent support. Another ugly way to initialize the storage would be to make liberal use of calloc() and free(). -- Chuck Karish karish@mindcraft.com Mindcraft, Inc. (415) 323-9000 Volume-Number: Volume 21, Number 22
