OutputStream.writeAll

bool writeAll(ubyte[] buffer, out size_t bytesWritten, gio.cancellable.Cancellable cancellable = null)

Tries to write count bytes from buffer into the stream. Will block during the operation.

This function is similar to [gio.output_stream.OutputStream.write], except it tries to write as many bytes as requested, only stopping on an error.

On a successful write of count bytes, true is returned, and bytes_written is set to count.

If there is an error during the operation false is returned and error is set to indicate the error status.

As a special exception to the normal conventions for functions that use #GError, if this function returns false (and sets error) then bytes_written will be set to the number of bytes that were successfully written before the error was encountered. This functionality is only available from C. If you need it from another language then you must write your own loop around [gio.output_stream.OutputStream.write].

Parameters

bufferthe buffer containing the data to write.
bytesWrittenlocation to store the number of bytes that was written to the stream
cancellableoptional #GCancellable object, null to ignore.

Returns

true on success, false if there was an error

Throws

[ErrorWrap]
