Deno.WriterSync - Deno documentation
interface Deno.WriterSync

This will be removed in Deno 2.0. See the Deno 1.x to 2.x Migration Guide for migration instructions.

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


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.
