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 pro-
     gram break is reliably returned by `sbrk(0)', see brk(2).
