END(3) Library Functions Manual END(3)
end, etext, edata - last locations in program
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 unini-
tialized 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)), the profile (-p) option of cc(1), etc. The current value
of the program break is reliably returned by `sbrk(0)', see brk(2).
