    Hi,
    With the change to ioo from aioo in AIX6(http://www.ibm.com/developerworks/aix/library/au-aix6tuning/index.html#N106A2), i am looking for way to get the aio_maxreqs using an API inside a program. On AIX5, i was able to get the same from ODM device using getattr.

    I suppose sysconf(_SC_AIO_MAX); doesn't give me the info i am looking for.

    o/p of C program with sysconf(_SC_AIO_MAX) = 4096.
    o/p of running ioo -a | grep aio_maxreqs : 65536
    Thanks for the help in advance.
