Hi all,

When loading an executable then segments like the code, data, bss and so on need to be placed in memory. I am just wondering, if someone could tell me where on a standard x86 for example the libc library is placed. Is that at the top or bottom of memory. My guess is at the bottom, close to the application code, ie., that would look something like this here:

---------  0x1000
Stack
  |
  V

  ^
  |
Heap
----------
Data + BSS
----------

App Code

----------

libc

---------- 0x0000

Thanks a lot, Ross
