     end, etext, edata — end boundaries of image segments

     extern end;
     extern etext;
     extern edata;

     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.

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

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