public virtual int BulkTransfer (Android.Hardware.Usb.UsbEndpoint? endpoint, byte[]? buffer, int length, int timeout);[<Android.Runtime.Register("bulkTransfer", "(Landroid/hardware/usb/UsbEndpoint;[BII)I", "GetBulkTransfer_Landroid_hardware_usb_UsbEndpoint_arrayBIIHandler")>]
abstract member BulkTransfer : Android.Hardware.Usb.UsbEndpoint * byte[] * int * int -> int
override this.BulkTransfer : Android.Hardware.Usb.UsbEndpoint * byte[] * int * int -> intParameters
- endpoint
- UsbEndpoint
the endpoint for this transaction
- buffer
- Byte[]
buffer for data to send or receive; can be null to wait for next
transaction without reading data
- length
- Int32
the length of the data to send or receive. Before
Build.VERSION_CODES#P, a value larger than 16384 bytes
would be truncated down to 16384. In API Build.VERSION_CODES#P
and after, any value of length is valid.
- timeout
- Int32
in milliseconds, 0 is infinite
Returns
length of data transferred (or zero) for success, or negative value for failure
- Attributes
Remarks
Performs a bulk transaction on the given endpoint. The direction of the transfer is determined by the direction of the endpoint.
This method transfers data starting from index 0 in the buffer. To specify a different offset, use #bulkTransfer(UsbEndpoint, byte[], int, int, int).
