65 | * get_tmpname() - create a tmp filename for a given filename | |

72 | * The tmp filename is basically the given filename with a |

74 | * put its unique gunk in). Take care to not exceed | |
75 | * either the MAXPATHLEN or NAME_MAX, esp. the last, as | |
76 | * the basename basically becomes 8 chars longer. In that | |
77 | * case, the original name is shortened sufficiently to | |
78 | * make it all fit. | |

52d3e106 S |
80 | * Of course, there's no real reason for the tmp name to |

82 | * As long as it's unique, rsync will work. | |
