END(3C) END(3C)
NAME
end, etext, edata - last locations in program
SYNOPSIS
extern end;
extern etext;
extern edata;
extern eprol;
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 is above the
initialized data region, end is above the uninitialized data
region, and eprol is the first instruction of the user's
program that follows the runtime startup routine.
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)), the profile (-p) option of cc(1),
etc. The current value of the program break is reliably
returned by `sbrk(0)', see brk(2).
