Arguments

 

format

   A pointer to a wide-character string containing the format
   specifications.
 

 . . .

   Optional expressions whose resultant types correspond to
   conversion specifications given in the format specification.

   If no conversion specifications are given, the output sources can
   be omitted. Otherwise, the function calls must have exactly as
   many output sources as there are conversion specifications, and
   the conversion specifications must match the types of the output
   sources.

   Conversion specifications are matched to output sources in left-
   to-right order. Excess output pointers, if any, are ignored.
