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

SYNOPSIS
       #include <allegro.h>

       int uvsprintf(char *buf, const char *format, va_list args);

DESCRIPTION
       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  over-
       flow the destination buffer. Use uvszprintf instead.

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