Wrong; the standard specifies that the errno shall only be
checked when the return value is -1.  The exception in the
strtol() case is only for presetting errno to 0 before you
make the call, and making a check only following a -1 return.

You cannot make assumptions about underlying implementations;
they may be either system calls or library routines, and your
application is not supposed to know or depend on which case
