splice

Description:

public virtual ssize_t splice (InputStream source, OutputStreamSpliceFlags flags, Cancellable? cancellable = null) throws IOError

Splices an input stream into an output stream.

Parameters:

this	a OutputStream.
source	a InputStream.
flags	a set of OutputStreamSpliceFlags.
cancellable	optional Cancellable object, null to ignore.

Returns:

a ssize_t containing the size of the data spliced, or -1 if an error occurred. Note that if the number of bytes spliced is greater than g_maxssize, then that will be returned, and there is no way to determine the actual number of bytes spliced.
