C# Class LibUsbDotNet.UsbEndpointReader

Contains methods for retrieving data from a EndpointType.Bulk or EndpointType.Interrupt endpoint using the overloaded Read(byte[],int,out int) functions or a DataReceived event.

Before using the DataReceived event, the DataReceivedEnabled property must be set to true. While the DataReceivedEnabled property is True, the overloaded Read(byte[],int,out int) functions cannot be used.

Method Details

Read() public method

Reads data from the current UsbEndpointReader.

public Read ( IntPtr buffer, int offset, int count, int timeout, int &transferLength ) : ErrorCode
buffer	System.IntPtr	The buffer to store the recieved data in.
offset	int	The position in buffer to start storing the data.
count	int	The maximum number of bytes to receive.
timeout	int	Maximum time to wait for the transfer to complete. If the transfer times out, the IO operation will be cancelled.
transferLength	int	Number of bytes actually transferred.
return	ErrorCode
