From allegro.txt:

int file_select(char *message, char *path, char *ext);
   Displays the Allegro file selector, with the message as caption. Allows 
   the user to select a file, and stores the selection in path.

So try something like:

   char path[80] = "";
   if (file_select("Choose a file", path, NULL))
      printf("file: %s\n", path);
   else
      printf("file selector was canceled\n");

The path parameter is used both for input and output: you can use it to 
set the initial path to display and an inital filename (eg. for a 'save 
as' operation where you want to start with the current name displayed), 
and the file selector changes it to whatever file is chosen. I know the 
docs aren't very clear on this, but I'm working on them. Version 2.01 is 
going to have more detailed explanations of things :-)
