END(3)			 BSD Library Functions Manual			END(3)

NAME
     end, etext, edata -- end boundaries of image segments

SYNOPSIS
     extern end;
     extern etext;
     extern edata;

DESCRIPTION
     The globals end, etext and	edata are program segment end addresses.

     etext is the first	address	after the end of the text segment.

     edata is the first	address	after the end of the initialized data segment.

     end is the	first address after the	end of the data	segment	(BSS) when the
     program is	loaded.	 Use the sbrk(2) system	call with zero as its argument
     to	find the current end of	the data segment.

SEE ALSO
     sbrk(2), malloc(3), a.out(5)

HISTORY
     An	end manual page	appeared in Version 6 AT&T UNIX.

BUGS
     Traditionally, no variable	existed	that pointed to	the start of the text
     segment because the text segment always started at	address	zero.  Al-
     though it is no longer valid to make this assumption, no variable similar
     to	the ones documented above exists to point to the start of the text
     segment.
