More man page reorganization.
Man pages need special handling, and we can have other kinds of documentation
like initial starting guides, etc., which would have different processing
applied. So lets move them off into their own directory.

The handle is initialized -with a completion callback of _callb_, which will be executed when an -associated asynchronous operation finishes. It will be called with the -argument _arg_. - -Asynchronous I/O operations all take an "aio" handle such as allocated by -this function. Such operations are usually started by a function that returns -immediately. The operation is then run asynchronously, and completes sometime -later. When that operation is complete, the callback supplied here is called, -and that callback is able to determine the result of the operation using -<<nng_aio_result#,nng_aio_result(3)>>, <<nng_aio_count#,nng_aio_count(3)>>, -and <<nng_aio_get_output#,nng_aio_get_output(3)>>. - -It is possible to wait synchronously for an otherwise asynchronous operation -by using the function <<nng_aio_wait#,nng_aio_wait(3)>>. In that case, -it is permissible for _callb_ and _arg_ to both be `NULL`. Note that if -these are `NULL`, then it will not be possible to determine when the -operation is complete except by calling the aforementioned -<<nng_aio_wait#,nng_aio_wait(3)>>. - -== RETURN VALUES - -This function returns 0 on success, and non-zero otherwise. - -== ERRORS - -`NNG_ENOMEM`:: Insufficient free memory to perform the operation. - -== SEE ALSO - -<<nng_aio_abort#,nng_aio_abort(3)>>, -<<nng_aio_cancel#,nng_aio_cancel(3)>>, -<<nng_aio_count#,nng_aio_count(3)>>, -<<nng_aio_free#,nng_aio_free(3)>>, -<<nng_aio_get_input#,nng_aio_get_input(3)>>, -<<nng_aio_get_msg#,nng_aio_get_msg(3)>>, -<<nng_aio_get_output#,nng_aio_get_output(3)>>, -<<nng_aio_result#,nng_aio_result(3)>>, -<<nng_aio_set_input#,nng_aio_set_input(3)>>, -<<nng_aio_set_iov#,nng_aio_set_iov(3)>>, -<<nng_aio_set_msg#,nng_aio_set_msg(3)>>, -<<nng_aio_set_timeout#,nng_aio_set_timeout(3)>>, -<<nng_aio_stop#,nng_aio_stop(3)>>, -<<nng_aio_wait#,nng_aio_wait(3)>>, -<<nng_strerror#,nng_strerror(3)>>, -<<nng#,nng(7)>> |
