Parameters

stream

The stream to test.

Returns

true if the stream can be written to.

Definition at line 241 of file as_stream.h.

References as_stream::hooks.

static as_stream_status as_stream_write ( const as_stream *  stream, as_val *  value  )

inlinestatic

Write a value to the stream

Parameters

stream	The stream to write to.
value	The element to write to the stream.

Returns

AS_STREAM_OK on success, otherwise is failure.
