NAME
       end, etext, edata - last locations in program

SYNOPSIS
       extern etext;
       extern etext;
       extern etext;

       extern edata;
       extern edata;
       extern edata;

       extern end;
       extern end;
       extern end;

DESCRIPTION
       These names refer neither to routines nor to locations with
       interesting contents; only their addresses are meaningful.

       etext, etext, etext
              The address of these symbols is the first address above the
              program text.

       edata, edata, edata
              The address of these symbols is the first address above the
              initialized data region.

       end, end, end
              The address of these symbols is the first address above the
              uninitialized data region.

SEE ALSO
       cc(1), brk(2), malloc(3C), stdio(3S).

NOTE
       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 brk and malloc, by standard input/output routines [see
       stdio(3S)], by the profile (-p) option of cc, and so on.  Thus, the
       current value of the program break should be determined by sbrk
       ((char *)0) [see brk(2)].
