Hi there, In Win32 there are several system calls that can be used to check whether pointers are vaild or not. They are called IsBadReadPointer, IsBadWritePointer, IsBadStringPointer, etc... I guess they work by checking the permission of the page of memory the pointers point to. I find them useful debugging tools and often write preconditions based on them as it is often better to check a pointer for readibility than simply checking for NULL. My question is: does the same thing exist in FreeBSD? Thanks for your help, Scott To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
