* Added an optional APR_POLLSET_NOCOPY flag for apr_pollset_create().brianp2005-10-231-47/+74
| | | | | | | | | | | | | | | | | | | | | This flag prevents the pollset implementation from making an internal copy of the descriptor object passed to apr_pollset_add(). Instead, a pointer to the descriptor itself is registered as the client_data for the underlying poll mechanism. This saves the cost of a copy, and in the case of the epoll-based implementation it eliminates the O(n)-time loop that's otherwise needed in apr_pollset_remove() to find and free the structure that contains a copy of the descriptor. Note that, when an application creates a pollset using APR_POLLSET_NOCOPY, the application must ensure that all descriptors passed to apr_pollset_add() have sufficiently long lifetimes. With this commit, the epoll-based implementation of apr_pollset implements the APR_POLLSET_NOCOPY optimization. The kqueue-based implementation would benefit from the same optimization. git-svn-id: http://svn.apache.org/repos/asf/apr/apr/trunk@327756 13f79535-47bb-0310-9956-ffa450edef68
