Thank you, John, Is this "offset of mapping" the last argument to mmap()? The following is 2 lines from the memory maps of process sshd: 40143000-40166000 r-xp 00000000 08:03 327696 /usr/lib/libglib-1.2.so.0.0.10 40166000-40167000 rw-p 00022000 08:03 327696 /usr/lib/libglib-1.2.so.0.0.10 I guess that the first line is for the code segment and the second line is for the data. The offset is 0x22000. I used "objdump -h" to show all the sections of the library. I found no section starting at 0x22000. So what should be at the offset in the file? Or my newbie's understanding is totally wrong? Thank you. Yue --- John Levon <levon@movementarian.org> wrote: > On Fri, Oct 04, 2002 at 07:37:08AM -0700, Yue Luo wrote: > > > Thank you.
