A symbol or string.
A symbol or string.
The class of the conversation object to create.
A boolean.
The function
dde-connect
attempts to create a conversation with a DDE server. If
server
names a client service registered with define-dde-client, the registered service name is used as the DDE service name. If
server
is any other symbol, the print name of the symbol is used as the DDE service name. If
server
is a string, that string is used as the DDE service name.
The topic argument specifies the DDE topic name to be used in the conversation. If it is a symbol, the symbol's print name is used. If it is a string, the string is used.
The
class
argument specifies the class of the conversation object to create. It must be a subclass of
dde-client-conversation
, or
nil
. If it is
nil
(the default value), then a conversation of class
dde-client-conversation
is created, unless
server
names a client service registered with define-dde-client, in which case the registered class (if any) is used.
On executing successfully, this function returns a conversation object. If unsuccessful, the behavior depends on the value of
errorp
. If
errorp
is
t
(the default value), then an error is raised. If
errorp
is false, the function returns
nil
.
Note that conversation objects may only be used within the thread (lightweight process) in which they were created.
