      NAME
           end, etext, edata - last locations in program

      SYNTAX
           extern end;
           extern etext;
           extern edata;

      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.

           When execution begins, the program break (the first location
           beyond the data) coincides with end, but the program break
           may be reset by the routines of brk(2), malloc(3C), standard
           input/output (stdio(3S)), the profile (-p) option of cc(1),
           and so on.  Thus, the current value of the program break
           should be determined by sbrk(0) (see brk(2)).

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