An abstract interface which when implemented provides an interface to write bytes from an array buffer to a file/resource synchronously.

Methods

writeSync(p: Uint8Array): number

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.
