Well, the problem with sscanf("%s", buf) is that the sscanf() don't know
how long is the buffer and that may lead to buffer overflow and strange
and unexpected behavior.
Generally there are two ways how to fix it. Either use GNU extension to
hardcode the maximal length of the buffer into the string, eg.
sscanf("%64s, buf); would say sscanf to use at most 64 bytes of the
buffer. Or go trough the string with while cycle till you find first
occurence of whitespace.
