44 | the trailing null) to the standard output stream. |
||
45 | |||
46 | The alternate function <<_puts_r>> is a reentrant version. The extra |

47 | argument <[reent]> is a pointer to a reentrancy structure. |

48 | |||
49 | RETURNS |
||
50 | If successful, the result is a nonnegative integer; otherwise, the |

51 | result is < |

54 | ANSI C requires < |

55 | success must be <<0>>; any non-negative value is permitted. |
