end(3C) end(3C)
NAME
end, etext, edata - last locations in program
SYNOPSIS
extern etext;
extern edata;
extern 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 address above the
program text.
edata The address of edata is the first address above the
initialized data region.
end The address of end is the first address above the
uninitialized data region.
REFERENCES
brk(2), cc(1), malloc(3C), stdio(3S)
NOTICES
When execution begins, the program break (the first location
beyond the data) coincides with end, but the program break may
be reset by the routines brk, malloc, the standard
input/output library [see stdio(3S)], by the profile (-p)
option of cc, and so on. Thus, the current value of the
program break should be determined by sbrk (0) [see brk(2)].
