The header defines all types and macros the same as
the C standard library header \libheader{stdint.h}.

except that the types \tcode{intptr_t} and \tcode{uintptr_t} and
the macros \tcode{INTPTR_MIN}, \tcode{INTPTR_MAX}, and \tcode{UINTPTR_MAX}

The types denoted by \tcode{intmax_t} and \tcode{uintmax_t}
are not required to be able to represent all values of extended integer types
wider than \tcode{long long} and \tcode{unsigned long long}, respectively.
