A named pipe stream.
A non-negative real number, or
nil
.
A string, or
nil
.
A function designator, or
nil
.
The function
wait-for-connection
waits until it succeeds to establish a connection for the stream
stream
, or
timeout
seconds passed or
wait-function
returns non-nil, and returns a value indicating whether the connection is established successfully.
stream must be a stream of the right type. Currently the only supported stream is a named pipe stream (the result of open-named-pipe-stream).
timeout
can be
nil
or a real number specifying the time in seconds before
wait-for-connection
returns without establishing a connection.
wait-reason , if non-nil, needs to be a string specifying the wait reason. It has the same semantics as the wait-reason argument of process-wait.
wait-function
, if non-nil, must be a function of no arguments. If it returns non-nil,
wait-for-connection
returns
nil
.
wait-for-connection
can be repeatedly called on the same stream. If the stream has already established a connection, it returns true immediately.
wait-function has the same limitations as the wait-function of process-wait.
