# end(3)

    NAME
         end, etext, edata - last locations in program

    SYNOPSIS
         extern int etext;
         extern int edata;
         extern int end, _end;

    DESCRIPTION
         These names refer neither to routines nor to locations  with  interesting
         contents.   The  address  of etext is the first address above the program
         text, edata  above  the  initialized  data  region,  and  end  above  the
         uninitialized  data  region.   _end  is  the  same  as  end,  but  in the
         implementers name space, i.e. for use in libraries.

         When execution begins, the program break coincides with end,  but  it  is
         reset   by   the   routines   brk(2),  malloc(3),  standard  input/output
         (stdio(3)), etc.  The current value of  the  program  break  is  reliably
         returned by `sbrk(0)', see brk(2).
