uvsprintf - Writes formatted data into a buffer, using variable arguments. Allegro game programming

       This is like usprintf(), but you pass the variable argument  list  directly,  instead  of  the  arguments
       themselves. You can use this function to implement printf like functions, also called variadic functions.
       You  should  try  to  avoid this function because it is very easy to overflow the destination buffer. Use
       uvszprintf instead.

       uvsprintf  -  Writes  formatted  data  into  a buffer, using variable arguments. Allegro game programming
       library.

       Returns the number of characters written, not including the terminating null character.
