Linux, can I specify port for outgoing udp packet?

Question

In one linux process there are several opened udp sockets for sending, each with no bind(). Is there any way to specify port for outgoing packet? Or raw sockets are the only way to do so?

Clarifying one moment: I have to have several separate sockets, so bind() is not an options.

Thanks, Alex.

Just call bind(). That's what it's for.
