>Sends a CLIENT_DATA_REQ event to the specified window. Used for requesting
both selection and "drag and drop" data. The mimetype argument specifies
the format of the data you would like to receive, as an index into the list
returned by GrGetSelectionOwner (the first type in the list is index 0).
The server makes no guarantees as to when, or even if, the client will
reply to the request. If the client does reply, the reply will take the
form of one or more CLIENT_DATA events. The request serial number is
typically a unique ID which the client can assign to a request in order for
it to be able to keep track of transfers (CLIENT_DATA events contain the
same number in the sid field). Remember to free the data field of the
CLIENT_DATA events as they are dynamically allocated. Also note that if
the allocation fails the data field will be set to NULL, so you should
check the value before using it.</P
