The contents and meaning of the header <cinttypes> are the same as the C standard library header <inttypes.h>, with the following changes:
  • The header <cinttypes> includes the header <cstdint> instead of <stdint.h>, and
  • if and only if the type intmax_­t designates an extended integer type, the following function signatures are added: intmax_t abs(intmax_t); imaxdiv_t div(intmax_t, intmax_t); which shall have the same semantics as the function signatures intmax_­t imaxabs(intmax_­t) and imaxdiv_­t imaxdiv(intmax_­t, intmax_­t), respectively.

Each of the PRI macros listed in this subclause is defined if and only if the implementation defines the corresponding typedef name in [cstdint.syn].
Each of the SCN macros listed in this subclause is defined if and only if the implementation defines the corresponding typedef name in [cstdint.syn] and has a suitable fscanf length modifier for the type.
