NAME
end, etext, edata - last location in program
USAGE
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(3), and so on. The current value of the
program break is reliably returned by calling sbrk(0).
