pollable_stream_write_all

Tries to write buffer.length bytes to stream, as with write_all, but using pollable_stream_write rather than write.

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

If there is an error during the operation (including g_io_error_would_block in the non-blocking case), false is returned and throws is set to indicate the error status, bytes_written is updated to contain the number of bytes written into the stream before the error occurred.

As with pollable_stream_write, if blocking is false, then stream must be a PollableOutputStream for which can_poll returns true or else the behavior is undefined. If blocking is true, then stream does not need to be a PollableOutputStream.

Parameters:

stream	a OutputStream.
buffer	the buffer containing the data to write.
blocking	whether to do blocking I/O
bytes_written	location to store the number of bytes that was written to the stream
cancellable	optional Cancellable object, null to ignore.
count	the number of bytes to write

Returns:

true on success, false if there was an error
