/prog/ - ncurses screen dump

Name: Anonymous 2009-08-18 15:48



void grand(int c)

{

  switch(c)

  {

    ...

    case 's':

      scr_dump("state");

      break;

    case 'l':

      scr_restore("state");

      break;

    case 'q':

      break;

  }

  move(row, col);

  refresh();

When I hit `s' the file with the data is created, but it isn't loaded after pushing `l'. What's wrong?

The scr_restore routine sets the virtual screen to the contents of filename, which must have been written using scr_dump. The next call to doupdate restores the screen to the way it looked in the dump file.

I've seen that. You can see refresh() in the code, which should do the same thing. Never-the-less, I tried the doupdate() anyway, but with no effect.

Character literals in C are just syntactic sugar for numeric literals.

There are curses macros(KEY_LEFT, etc.)in the snipped part of the code, and they are too big for a char.

Implying there is anything sugary about C syntax
IHBT.

Weak typing != syntactic sugar

Indeed. Weak typing would be if someone tried to store 's' in a char.

Do you think I'm an idiot? Take tips like this to ubantoforums.
- have you read your sicp today?
Actually, I have.

You started a thread advertising that you're too dumb to operate ncurses. Was he wrong to believe you?

Yes.

You don't seem to know what's wrong either.

This may surprise you, but we can't guess what your error is from a simple snippet of code that doesn't have any error in it. You should be able to.
