Original commit message from CVS: 2005-03-03 Andy Wingo <wingo@pobox.com> * tools/gst-launch.c: Update to use the new message-parsing API. * tools/gst-md5sum.c: Update to new spiffy poll API. Not that md5sum is ported though! * gst/gstmessage.c: * gst/gstmessage.h (struct _GstMessage): Changed so the message data is just a GstStructure, not a union. (gst_message_get_structure): New function, gets the structure backing the message. Owned by the message. (gst_message_parse_tag, gst_message_parse_state_changed) (gst_message_parse_error, gst_message_parse_warning): New functions, parse the message into their components. Return values are copies, and so must be freed by the caller.
