 There's no API to allocate an anchor. It is simply declared

 ===================================================
 
 An association of URBs to an anchor is made by an explicit
-call to usb_anchor_urb(). The association is maintained until
+call to :c:func:`usb_anchor_urb`. The association is maintained until
 an URB is finished by (successful) completion. Thus disassociation
 is automatic. A function is provided to forcibly finish (kill)
 all URBs associated with an anchor.

 Operations on multitudes of URBs
 ================================
 
-usb_kill_anchored_urbs()
-------------------------
+:c:func:`usb_kill_anchored_urbs`
+--------------------------------
 
 This function kills all URBs associated with an anchor. The URBs
 are called in the reverse temporal order they were submitted.
 This way no data can be reordered.
 
-usb_unlink_anchored_urbs()
---------------------------
+:c:func:`usb_unlink_anchored_urbs`
+----------------------------------

 This function unlinks all URBs associated with an anchor. The URBs
 are processed in the reverse temporal order they were submitted.
-This is similar to usb_kill_anchored_urbs(), but it will not sleep.
+This is similar to :c:func:`usb_kill_anchored_urbs`, but it will not sleep.
 Therefore no guarantee is made that the URBs have been unlinked when
 the call returns. They may be unlinked later but will be unlinked in
 finite time.
 
-usb_scuttle_anchored_urbs()
----------------------------
+:c:func:`usb_scuttle_anchored_urbs`
+-----------------------------------
 
 All URBs of an anchor are unanchored en masse.
 
-usb_wait_anchor_empty_timeout()
--------------------------------
+:c:func:`usb_wait_anchor_empty_timeout`
+---------------------------------------
 
 This function waits for all URBs associated with an anchor to finish
 or a timeout, whichever comes first. Its return value will tell you
 whether the timeout was reached.
 
-usb_anchor_empty()
-------------------
+:c:func:`usb_anchor_empty`
+--------------------------
 
 Returns true if no URBs are associated with an anchor. Locking
 is the caller's responsibility.
 
-usb_get_from_anchor()
----------------------
+:c:func:`usb_get_from_anchor`
+-----------------------------
 
 Returns the oldest anchored URB of an anchor. The URB is unanchored
 and returned with a reference. As you may mix URBs to several
