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 re-
       turned by `sbrk(0)', see	brk(2).

SEE ALSO
       brk(2), malloc(3)
