563 | * @argc: Number of arguments | |
564 | * @argv: Array of string arguments | |
565 | * @parsed: Pointer to return the number of used arguments, or NULL to error | |
566 | * out if any argument is left unused. | |

568 | * The given chandef structure will be filled in from the command line | |

570 | * command line can be parsed. | |

573 | * are needed, there's an ambiguity if the next argument after this is an | |
574 | * integer argument, since the valid channel width values are interpreted | |
575 | * as such, rather than a following argument. This can be avoided by the | |
576 | * user by giving "NOHT" instead. | |
997c60fd BB |

578 | * The working specifier if chan is set are: | |

997c60fd BB |

584 | * | |
