END(3)                  GENIX Programmer's Manual                  END(3)



      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 coincides with end, but  it
           is  reset  by  the routines 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).
