Passing too many arguments to printf

by

Online C Draft Standard (n1256), section 7.19.6.1, paragraph 2:

The fprintf function writes output to the stream pointed to by stream, under control of the string pointed to by format that specifies how subsequent arguments are
converted for output. If there are insufficient arguments for the format, the behavior is
undefined. If the format is exhausted while arguments remain, the excess arguments are
evaluated (as always) but are otherwise ignored. The fprintf function returns when
the end of the format string is encountered.

Behavior for all the other *printf() functions is the same wrt excess arguments except for vprintf() (obviously).
