Hello Looking at this page: http://man7.org/linux/man-pages/online/pages/man3/printf.3.html "If an output error is encountered, a negative value is returned."I am thinking if this could be clarified. If I call printf(NULL), errno is set to EINVAL, and -1 is returned.
Perhaps could be expanded to add:"If a parameter error is encountered, errno set to EINVAL, and -1 is returned. If an output error is encountered, errno set EIO and -1 returned.
