Reads data from this channel into buffer, returning the number of bytes read.
Reads data from this channel into buffer, returning the number of bytes read.
Fails with
java.io.EOFExceptionif end-of-stream is reached.- position
The file position at which the transfer is to begin; must be non-negative

sink(position: Long, bufferConstruct: UIO[ByteBuffer])(implicit trace: Trace): ZSink[Any, IOException, Byte, Byte, Long]
A sink that will write all the bytes it receives to this channel.
A sink that will write all the bytes it receives to this channel. The sink's result is the number of bytes written.
- position
The position in the file the sink will write to.
- bufferConstruct
Optional, overrides how to construct the buffer used to transfer bytes received by the sink to this channel. By default a heap buffer is used, but a direct buffer will usually perform better.

The position in the file the stream will read from.
- bufferConstruct
Optional, overrides how to construct the buffer used to transfer bytes read from this channel into the stream. By default a heap buffer is used, but a direct buffer will usually perform better.

writeChunk(src: Chunk[Byte], position: Long)(implicit trace: Trace): IO[IOException, Unit]
Writes a chunk of bytes at a specified position in the file.
Writes a chunk of bytes at a specified position in the file.
More than one write operation may be performed to write the entire chunk.
- src
The bytes to write.
- position
Where in the file to write.
