DESCRIPTION    [Toc]    [Back]

     These interfaces are available from the compatibility library, libcompat.


     insque() and remque() manipulate queues built from doubly linked lists.
     Each element in the queue must begin with a "struct qelem".

     These functions are not atomic unless that machine architecture allows
     it.

HISTORY    [Toc]    [Back]
