toWritePipe abstract method
Extracts a write pipe from resource handle.
Since the ResourceHandle represents a single OS resource, none of toFile, toSocket, toRawSocket, or toRawDatagramSocket, toReadPipe, toWritePipe, can be called after a call to this method.
If this resource handle is not a writeable pipe, the behavior of the returned ReadPipe is completely unspecified. Be very careful to avoid using a handle incorrectly.
Implementation
WritePipe toWritePipe();
