Re: questions about /proc/<pid>/map

[Yue Luo <ecelca@yahoo.com>]

  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.
