 
The generic function 
dde-server-poke
 is called in response to a poke transaction. A method specializing on the classes of 
server
 and 
topic
 should poke the data given by 
data
 into the item specified by 
item
.
The keyword 
format
 indicates the format in which the item is being requested. By default, only text transfers are supported (and the 
format
 argument will have the value 
:text
).
The set of supported formats may be extended in future releases, so applications should always check the value of the format parameter and reject transactions which use formats not supported by the application.
If the poke transaction is successful, non-
nil
 should be returned, and 
nil
 should be returned for failure.
