Yes. Or even 0->127, since $? in the shell is 128 + signal number when
the process died due to signal. No idea if that's standard or a
deliberate bash feature or what, or if it's just lazy OS-dependent code.
For other codes, we'd return that special code. Or maybe just translate
them to LDAP_OTHER. I seem to remember there were some result codes
reserved for the API (around code 80?), but cannot find that.
There are also OSes (VMS?) where exit status of 0 produces a failure
termination status and/or where some nonzero exit statuses mean success.
There, the C code exit(0) and exit(EXIT_SUCCESS) is turned into some
success termination status in the OS, and exit(EXIT_FAILURE) gives some
failure. The termination status from other exit() arguments is not
specified by the C standard. I have no idea if such an OS exists to
which it is feasible to port OpenLDAP.
