WritableByteChannel represents an output resource (i.e file) which could be used to sink bytes
A file path can be used to obtain a
io:WritableByteChannel can only be obtained using the following method or by providing a native implementation.
It cannot be instantiated.
io:openWritableFile("./files/sample.txt") - used to obtain a
io:WritableByteChannel from a given file path
Sinks bytes from a given input/output resource.
This is an asynchronous operation. The method might return before writing all the content.
1int|io:Error result = writableByteChannel.write(record, 0);
- content byte[ ]
Block of bytes to be written
- offset int
Offset of the provided content, which needs to be kept when writing bytes
