/** Retrieves the UID of the callee. This function retrieves the UID (unique

* identifier) of the party being called. The function first searches the list
|
|
* of available attributes and if it finds an attribute with name "uid" then
|
|
* the value of the attribute is returned. If no such attribute can be found
|
|
* then the function retrieves the username from To header field of REGISTER
|
|
* requests (because that is the party being registered), or the username from
|
|
* the Reqeuest-URI of other requests. The username is then used as the UID
|
|
* string identifying the callee. If no attribute with the UID was found and
|
|
* the function successfully retrieved the UID from the SIP message then, in
|
|
* addition to storing the result in the first parameter, the function will
|
|
* also create the attribute named "uid" which will contain the UID. The
|
|
* function is not reentrant because it uses an internal static buffer to
|
|
* store the result.
|
|
* @param uid A pointer to ::str variable where the result will be stored, the
|
|
* pointer in the variable will be updated to point to a static
|
|
* buffer in the function.
|
|
* @param msg The SIP message being processed.
|
|
* @return 1 is returned when the attribute with UID exists and it is used, 0
|
|
* is returned when the function retrieved the UID from the SIP
|
|
* message and created the attribute, -1 is returned on error.
