[Octave-bug-tracker] [bug #49779] print /non/existing/dir/file.svg crashes octave

[Avinoam Kalma]

Follow-up Comment #7, bug #49779 (project octave):

What about the following check:


folder = fileparts (opts.name);
  if (~isempty(folder))
      if (~exist(folder,'dir'))
        str = sprintf ('print: directory %s does not exist', folder);
        error (str);
      end
  end
  
  fid = fopen (opts.name, 'w')
  if (fid == -1)
    str = sprintf ('print: cannot open file %s for writing',  opts.name);
    error (str);
  end
  fclose (fid);


It is close to Pantxo suggestion (comment#4), and solves this bug and
bug#50146. I know that this not the desired solutions, and does not solve
other expected and unexpected situations, it can
give an interim fix.
