Name
       end, etext, edata - last locations in program

Syntax
       extern end;
       extern etext;
       extern edata;
       extern eprol;

Description
       These  names  refer  neither to routines nor to locations with interesting contents.  The address of is the first address above the program
       text, above the initialized data region, and is the first instruction of the user's program that follows the runtime startup routine.

       When execution begins, the program break coincides with but it is reset by the routines standard input/output the profile  (-p)	option	of
       and so forth.  The current value of the program break is reliably returned by sbrk(0).  For further information, see

NAME

       end, _end, etext, _etext, edata, _edata - last locations in program

SYNOPSIS

       extern int _etext;

       extern int _edata;

       extern int _end;

DESCRIPTION

       These names refer neither to routines nor to locations with interesting contents; only their addresses are meaningful.

       _etext	       The address of _etext is the first location after the program text.

       _edata	       The address of _edata is the first location after the initialized data region.

       _end	       The address of _end is the first location after the uninitialized data region.

USAGE

       When  execution	begins,  the program break (the first location beyond the data) coincides with _end, but the program break may be reset by
       the  brk(2), malloc(3C), and the standard input/output library (see stdio(3C)), functions by the profile (-p) option of	cc(1B), and so on.
       Thus, the current value of the program break should be determined by sbrk ((char *)0).

       References  to  end,  etext, and edata, without a preceding underscore will be aliased to the associated symbol that begins with the under-
       score.
