WebIf the application attempts to read more than this returned length, it will get garbage (or a segmentation fault). To avoid reading over this limit, it is usual to put a NULL value at position buf [siz] right after the siz=recvfrom (...) call. This way, any later function call that uses buf as a string will work properly.
