al_fread16be - Allegro 5 API

       Reads a 16-bit word in big-endian format (MSB first).

       On  success,  returns  the  16-bit  word.  On failure, returns EOF (-1).  Since -1 is also a valid return
       value,  use  al_feof(3alleg5)  to  check  if  the  end  of  the  file   was   reached   prematurely,   or
       al_ferror(3alleg5) to check if an error occurred.
