The inttypes.h header includes definitions of, at least, the following types:

int8_t | 8-bit signed integral type. |

int16_t | 16-bit signed integral type. |

int32_t | 32-bit signed integral type. |

int64_t | 64-bit signed integral type. |

uint8_t | 8-bit unsigned integral type. |

uint16_t | 16-bit unsigned integral type. |

uint32_t | 32-bit unsigned integral type. |

uint64_t | 64-bit unsigned integral type. |

intptr_t | Signed integral type large enough to hold any pointer. |

uintptr_t | Unsigned integral type large enough to hold any pointer. |
