+
+[`vprintf` functions](vprintf-functions.md)\
+The `vprintf` functions take a pointer to an argument list, formats it, and writes the result to the specified destination. The functions differ in the parameter validation performed, whether they take wide or single-byte character strings, the output destination, and support for specifying the order in which parameters are used in the format string.
