LispWorks clients can issue request and poke transactions across a conversation using dde-request and dde-poke , which take a conversation (or a service designator/ topic designator pair in the case of an automatically managed conversation), and an item as their main arguments. In the case of a poke transaction, data to be poked into item must also be provided.
In the case of a successful request transaction with dde-request or dde-request* , the data contained in item is returned to the LispWorks client by the server.
In the case of a successful poke transaction with dde-poke or dde-poke* , the data provided is poked into item by the server.
The accessor dde-item (or dde-item* for automatically managed conversations) can perform request and poke transactions. See the LispWorks Reference Manual for more details.
dde-item conversation item &key format type errorp The accessor dde-item performs a request transaction when read. It performs a poke transaction when set.
dde-poke conversation item data &key format type errorp => result The function dde-poke issues a poke transaction on conversation to set the value of the item specified by item to the value specified by data . The argument item should be a string, or a symbol. If it is a symbol its print name is used.
dde-request conversation item &key format type errorp The function dde-request issues a request transaction on conversation for the specified item . The argument item should be a string, or a symbol. If it is a symbol its print name is used.
