An abstract interface which when implemented provides an interface to write bytes from an array buffer to a file/resource synchronously.
p.byteLength bytes from
p to the underlying data
stream. It returns the number of bytes written from
p.byteLength) and any error encountered that caused the write to
writeSync() must throw a non-null error if it returns
writeSync() must not modify the slice data, even
