octave: libinterp/corefcn/syscalls.cc annotate

annotate libinterp/corefcn/syscalls.cc @ 28102:4d021e0dcfee

fcntl: throw error if operation fails and nargout == 0 (bug #57830). * syscalls.cc (Ffcntl): Add nargout to DEFUN macro invocation. Add command calling form to documentation. Rename "err" to "status" in documentation. Document that status variable is -1 if an error is encountered. Based on nargout variable, either throw an error if operation failed, or return status and msg information.
