Deprecated
Use WritableStream instead. WriterSync
will be removed in v2.0.0.
An abstract interface which when implemented provides an interface to write bytes from an array buffer to a file/resource synchronously.
Methods
Writes p.byteLength bytes from p to the underlying data
stream. It returns the number of bytes written from p (0 <= n
<= p.byteLength) and any error encountered that caused the write to
stop early. writeSync() must throw a non-null error if it returns n <
p.byteLength. writeSync() must not modify the slice data, even
temporarily.
Implementations should not retain a reference to p.
