WDF_USB_CONTROL_SETUP_PACKET_INIT 函数初始化标准 USB 控制传输的 WDF_USB_CONTROL_SETUP_PACKET 结构。语法C++ 复制 void WDF_USB_CONTROL_SETUP_PACKET_INIT( [out] PWDF_USB_CONTROL_SETUP_PACKET Packet, [in] WDF_USB_BMREQUEST_DIRECTION Direction, [in] WDF_USB_BMREQUEST_RECIPIENT Reci...
void NET_ADAPTER_WAKE_REASON_PACKET_INIT( [_Out_] NET_ADAPTER_WAKE_REASON_PACKET *Reason ); 参数 [_Out_] Reason 指向分配NET_ADAPTER_WAKE_REASON_PACKET结构的驱动程序的指针。 返回值 无 备注 此函数将NET_ADAPTER_WAKE_REASON_PACKET结构的内存归零,然后设置Size成员。
WDF_USB_CONTROL_SETUP_PACKET_INIT_GET_STATUS函数执行以下作: 零WDF_USB_CONTROL_SETUP_PACKET结构。 将Packet.bm.Request.Type成员设置为BmRequestStandard。 将Packet.bm.Request.Dir成员设置为BmRequestDeviceToHost。 将Packet.bRequest成员设置为“获取状态”请求值。
voidACX_RTPACKET_INIT( PACX_RTPACKET RtPacket ); 参数 RtPacket ACX_RTPACKET结构。 返回值 无 备注 示例 C++ packets = (PACX_RTPACKET)ExAllocatePool2(POOL_FLAG_NON_PAGED, packetsSize, DRIVER_TAG); RETURN_NTSTATUS_IF_TRUE(!packets, STATUS_NO_MEMORY); ... ACX_RTPACKET_INIT(&packets[i]);...
The WDF_USB_CONTROL_SETUP_PACKET_INIT_GET_STATUS function initializes a WDF_USB_CONTROL_SETUP_PACKET structure for a USB control transfer that obtains device status.
The WDF_USB_CONTROL_SETUP_PACKET_INIT_CLASS function initializes a WDF_USB_CONTROL_SETUP_PACKET structure for a device class-specific USB control transfer.
Checksum 32 bits This field contains the checksum of this SCTP packet. SCTP uses the Adler-32 algorithm for calculating the checksum. Type 8 bits Type = 1: Initiation (INIT) Chunk Flags 8 bits The usage of these bits depends on the chunk type as given by the Chunk Type. Unless otherwise...
