annotate libinterp/octave-value/ov-builtin.h @ 23653:3bb0a937c071
avoid possible memory errors when parsing function files
* ov-builtin.h (octave_builtin::call): Provide default values for
nargout and args in declaration.
* ov-mex-fcn.h (octave_mex_function::call): Likewise.
* ov-usr-fcn.h (octave_user_function::call): Likewise.
* parse.h, oct-parse.in.yy (parse_fcn_file, load_fcn_from_file):
Return octave_value object instead of raw pointer to octave_function.
Change all uses.
