The precision, if any, gives the minimum number of digits that must appear; if the converted value requires fewer digits, it is padded on the left with zeros. The default precision is 1. When 0 is printed with an explicit precision 0, the output is empty. .It o, u, x, X (ell) A following integer conversion corresponds to a long or unsigned long argument, or a following n conversion corresponds to a pointer to a long argument, or a following c conversion corresponds to a wint_t argument, or a following s conversion corresponds to a pointer to wchar_t argument. .It S Non printable characters (0 < ASCII value < 32 or >= 127) are printed this way: \x, followed by the ASCII code value in hexadecimal (upper case - always 2 characters). .It c print char. .It o, u, x, X (Not in C99 or C11, but in SUSv2, SUSv3, and SUSv4.)
