The main thing to watch out for it people using int's as pointers. pointers should always be void * or longs. Do you have an example of how to make it segfault? > Unfortunately often I don't know when a data structure can be freed. When you know you won't try to access it again. Also setting the pointer to NULL after freeing it and then checking that a pointer is not NULL before trying to access it (and if it is null when you don't think it should be, spit out an error message). -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
