arrays. The MPI 3.0 standard added const to all in buffers in the C bindings. This commit adds the const keyword and in most cases casts const away. We will eventually should go through and update the various interfaces (coll, pml, io, etc) to take the const keyword. The group, comm, win, and datatype interfaces have been updated with const. cmr=v1.7.4:ticket=trac:3785:reviewer=jsquyres This commit was SVN r29266.

|
* Failure to connect will be indicated by a callback returning a NULL communicator. Callers
|
|
* should use the cbdata to track the corresponding pconnect request. A timeout
|
|
* is provided to avoid hanging should the other process not have an active paccept
|
|
* on the specified port (e.g., the process may have closed it). A NULL value for
|

* the timeout argument indicates that the pconnect operation should not timeout,

*
|
|
* Processes may create and publish as many ports, and call paccept as many times, as
|
|
* they like. When a process no longer wishes to accept connect requests, it can "close"
|
|
* a paccept request by passing in the port used when calling paccept. A call to "close"
|
|
* with a NULL argument will close *all* currently registered paccept channels.
