Question

I want to get private messages (provided by the Privatemsg module) that are related to a particular user, programatically.

How can I do this?

Answer 1

Private messages are entities so you can use entity_load() to load them by condition…or use the wrapper provided by the private message module itself:

$messages = privatemsg_message_load_multiple(array(), array('author' => $uid));

That will get all messages created by the user identified by $uid.
