END(3C)              INTERACTIVE UNIX System              END(3C)



          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 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 ((char *)0) [see brk(2)].

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