perldoc -f connect
connect SOCKET,NAME
Attempts to connect to a remote socket, just as the connect system call does. Returns true if it succeeded, false otherwise. NAME should be a packed address of the appropriate type for the socket. See the examples in "Sockets: Client/Server Communication" in perlipc.

Either you mean a connect() method of some (to us unknown) class or you did not bother reading the docs. The builtin connect() is for SOCKETS not named pipes. Maybe you meant select(). Though that doesn't tell you whether a client "connected" to a named pipe (whatever would that mean), but whether there is anything to read from the pipe.

A když jsme tak u toho ty chytráku, já té tvojí zpotvořené hatmatilce rozumím bez problémů, co si ovšem počneš s tímhle by mě fakt zajímalo.
