118 The following file operations are supported: open, release, read, poll.
119 There are two alternative methods for reading: either non-blocking read in
120 conjunction with polling, or blocking read without polling. IOCTLs are not

148 <0 byte read>
153 read with a return value of 0 (0 byte read).
155 read successfully, including the closing 0 byte read. Therefore you should
156 always read the complete set into a buffer before processing the data.
165 negative value for the number of bytes read. In this case, the errno variable
168 EIO: reply failed, read data is invalid and the application
169      should discard the data read since the last successful read with 0 size.
170 EFAULT: copy_to_user failed, read data is invalid and the application should
171         discard the data read since the last successful read with 0 size.
172 EAGAIN: occurs on a non-blocking read if there is no data available at the
175 EOVERFLOW: message limit reached, the data read since the last successful
176            read with 0 size is valid but subsequent records may be missing.
