--- Comment #4 from Tom Hughes <t...@compton.nu> --- Well that one doesn't need a PRE_MEM_READ so the fact that it would complain isn't really relevant. You should use PRE_MEM_READ before the system call for any memory which will be read by the system call and PRE_MEM_WRITE for any memory which will be written by the system call (unless it is also read - you don't need to do both). After the system call completes you should use POST_MEM_WRITE on any memory that the system call has written. Basically PRE_MEM_READ checks that the memory is both addressable (that there is actual accessible memory at that address) and defined (that it has been initialised with known contents) while PRE_MEM_WRITE just does the first check. Then POST_MEM_WRITE marks the memory as defined if it has been filled in by the system call. -- You are receiving this mail because: You are watching all bug changes.
