END(3)                               BSD                                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).
