驱动程序可以使用以下宏设置与 评估控件方法的 ACPI IOCTL 一起使用的输入参数：
ACPI_METHOD_SET_ARGUMENT_INTEGER
ACPI_METHOD_SET_ARGUMENT_STRING
ACPI_METHOD_SET_ARGUMENT_BUFFER
The ACPI IOCTLs that evaluate control methods return output arguments in the Argument member of an ACPI_EVAL_OUTPUT_BUFFER structure, where the Argument member is an array of ACPI_METHOD_ARGUMENT structures. 驱动程序可以使用以下宏来帮助处理ACPI_METHOD_ARGUMENT结构的数组：
ACPI_METHOD_ARGUMENT_LENGTH_FROM_ARGUMENT
An IOCTL_ACPI_ENUM_CHILDREN request retrieves the path and name of child objects in the namespace of the device to which the request is sent. ACPI 驱动程序返回以 ACPI 命名空间根开头的枚举对象的完整路径和名称。 The path and name of the child objects are returned in the Children member of an ACPI_ENUM_CHILDREN_OUTPUT_BUFFER structure, where the Children member is an array of ACPI_ENUM_CHILD structures. 驱动程序可以使用以下宏来帮助处理ACPI_ENUM_CHILD结构的数组：
