NAME
       end, etext, edata - last locations in program

SYNOPSIS
       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 unini-
       tialized data region.

       When execution begins, the program break coincides with end,  but  many
       functions  reset  the program break, among them the routines of brk(2),
       malloc(3), standard input/output (stdio(3)), the profile (-p) option of
       cc(1),  etc.   The  current  value  of  the  program  break is reliably
       returned by `sbrk(0)', see brk(2).

SEE ALSO
       brk(2), malloc(3)
