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
uninitialized data region.
When execution begins, the program break (the first location beyond the
data) coincides with end, but it is reset by the routines brk(2), mal-
loc(3V), standard input/output (stdio(3V)), the profile (-p) option of
cc(1V), and so on. Thus, the current value of the program break should
be determined by sbrk(0) (see brk(2)).
cc(1V), brk(2), malloc(3V), stdio(3V)
