Namespace:
Android.Hardware.Usb
Assembly:
Mono.Android.dll

Overloads

BulkTransfer(UsbEndpoint, Byte[], Int32, Int32)

Performs a bulk transaction on the given endpoint.
BulkTransfer(UsbEndpoint, Byte[], Int32, Int32, Int32)

Performs a bulk transaction on the given endpoint.

BulkTransfer(UsbEndpoint, Byte[], Int32, Int32)

Performs a bulk transaction on the given endpoint.

[Android.Runtime.Register("bulkTransfer", "(Landroid/hardware/usb/UsbEndpoint;[BII)I", "GetBulkTransfer_Landroid_hardware_usb_UsbEndpoint_arrayBIIHandler")]
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 -> int

Parameters

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

Int32

length of data transferred (or zero) for success, or negative value for failure

Attributes
RegisterAttribute

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).
