This is a utility function around OutputStream.writeAll. It uses g_strdup_vprintf() to turn format and args into a string that is then written to stream.

See the documentation of OutputStream.writeAll about the behavior of the actual write operation.

Note that partial writes cannot be properly checked with this function due to the variable length of the written string, if you need precise control over partial write failures, you need to create you own printf()-like wrapper around OutputStream.write or OutputStream.writeAll.
