Hello, Everyone! I am working on a game, and I need to re-write the file
loading from the orginal 3D engine. Here is the old routine and the one that
I am having trouble with.  Any help would be greatly appreciated!

The old one:

long int FileRead(char *Name, long int Start, long int Len, void *buffer)
{
      int handle;
      long int size;

      handle=open(Name,O_RDONLY|O_BINARY);
      lseek(handle,Start,SEEK_SET);
      size=read(handle,buffer,Len);
      close(handle);
      return(size);
}

And here is mine that fails at _pack_fread :

long int FileRead(char *Name, long int Start, long int Len, void *buffer)
{
        PACKFILE *the_file;
        char mFilename[20];
        long int size;

        sprintf( mFilename, "data.dat#%s", Name );
        textout( screen, font, mFilename, 10, 10, 10 );
        while( !keypressed() );
        the_file=pack_fopen( mFilename, F_READ );
        pack_fseek( the_file, Start );
        size=pack_fread( buffer, Len, the_file );
        pack_fclose(the_file);
        return(size);
}

I also changed the file names that are passed to the function so that it is
a '_' instead of a '.' (ie, "MYDATA_BIN" op. "MYDATA.DAT" )
It is saved with the grabber util with no compression and no password.
Thanks again!
