END(3)		    UNIX 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(3S)), 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)
