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 pro-
       gram 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).

SEE ALSO
       brk(2), malloc(3).
