How to give a packfile a name?

How to give a packfile a name?

While doing a map editor for the RPG we're making, we've found that it would be very convenient to be able to give the packfiles we use a name during the editing, and not having to go back to the code to do it, could anyone point out how? Here's an example of the function we're using:

1void save_map()
2{
  PACKFILE *pfile;
     
  pfile=pack_fopen("mapaprueba.map", "wp");   
      for (m=0; m<1; m++)
      {
      for (k=0; k<2; k++)
      {
      for (l=0; l<2; l++)
      {
      for (i=0; i<32; i++)
      {
      for (j=0; j<24; j++)
      {        
             pack_iputl(mapa.grid<i>[j].tile[k][l].capas[m], pfile);
      }        }        }        }        }
  pack_fclose(pfile);
19}

What we would like to do is to somehow put the name of the map form the editor not the compiler. We'd really appreciate it if anyone points us in the right direction . TXS!!
Cheers.

void save_map(char *filename)
{
 PACKFILE *pfile;
       
 pfile=pack_fopen(filename, "wp");
 [...]
}

save_map("mapaprueba.map");

But that doesn't even compile...

Txs people, you are right dint think of that... not to used to think in C... anyone could point me out to some functions the allegro has for managing user input (its for the same thing, now that i can change the name the file has, i want th user to be able to do it by himself)

Txs a lot... I'm relay sorry to have to come back to ask over and over again

Cheers!

there are none beside the allegro GUI stuff but here some code from Chris he thought up a way to do it.
it was in the code gallery.

edit: the file seems to have lostest it host i think i down loaded it befor ill find it and post it.;D

edit:

if your looking for more examples of stuff check out my game in the Projects RPG area.
it is very up-to date. don't be to shy to wright a review . good luck;;D

Or you can use a save file dialog...

if(insert) insert = 0; else insert = 1;

Imo this is much cleaner

insert = !insert;

What about home and end? Personally I think insert is more of an annoance then a feature, and you support it but not home and end? shame on you.

Anyway, you also forgot about two important things. 1) The box scroll! The text inside an input widget needs to scroll to the left and right so that the user sees the correct data inside the box. And 2) clicking to move the caret. There doesnt seem to be a way to click somewhere to get the caret to move there.

Anyway, heres some code ripped out of my Input widget. Its a bit dependent on internal frameworks and such, but it hopefully conveys the idea.

1Input::Action Input::onIdle()
2{
  string &value = attributes["value"];
  
  if(hasFocus && keypressed()) {
      
      int val = readkey();
      
      if((val >> 8) == KEY_ENTER && attributes.count("enterAction")) {
          
          GuiScreen::active->generateAction(attributes["enterAction"], this);
      }
      else if((val >> 8) == KEY_BACKSPACE) {
          
          if(cursorPos != 0 && !value.empty()) {
              
              value.erase(cursorPos - 1, 1);
              
              setCursorPos(cursorPos - 1);
              boundsCheckScroll();
          }
      }
      else if((val >> 8) == KEY_DEL) {
          
          if(cursorPos < (signed)value.size() && !value.empty()) {
              
              value.erase(cursorPos, 1);
              
              setCursorPos(cursorPos);
              boundsCheckScroll();
          }
      }
      else if((val >> 8) == KEY_LEFT) {
          
          setCursorPos(cursorPos - 1);
      }
      else if((val >> 8) == KEY_RIGHT) {
          
          setCursorPos(cursorPos + 1);
      }
      else if((val >> 8) == KEY_HOME) {
          
          setCursorPos(0);
      }
      else if((val >> 8) == KEY_END) {

      }
      else if(val & 0xff) {
          
          if(!attributes.count("restrictTo") || attributes["restrictTo"].find((char)(val & 0xff)) != string::npos) {
              
              value.insert(cursorPos, 1, val & 0xff);
              setCursorPos(cursorPos + 1);

It also supports variable width fonts, which is why there are setCursorPos and getCursorPos functions.
