commonc++ 0.4.5 (Default branch)
commonc++ is a C++ class library for developing cross-platform systems software for POSIX and Windows systems. It provides an intuitive, object-oriented abstraction and portability layer around common operating system facilities like threads, concurrency mechanisms, sockets, networking, shared memory and other IPC mechanisms, regular expressions, files, streams, logging, process execution, scheduling, and more. It also includes a collection of common abstractions like strings, buffers, and object pools. License: GNU Lesser General Public License (LGPL) Changes:
This release includes a few API enhancements and a large number of bugfixes.Image

aio_prio_delta_max

aio_prio_delta_max(5)						File Formats Manual					     aio_prio_delta_max(5)

NAME

       aio_prio_delta_max - greatest delta (slowdown factor) allowed in POSIX async IO request priorities

VALUES

   Failsafe
   Default
   Allowed values
       The minimum value allowed is The maximum value allowed is

       Specify a positive integer value.

DESCRIPTION

       This  parameter	places a limit on how much the priority of a POSIX asynchronous I/O operation can be reduced to slow it down.  This is the
       maximum priority-offset value allowed for in the asynchronous-I/O control block structure

   Who Is Expected to Change This Tunable?
       System administrators that run applications requiring heavy usage of POSIX AIO to file systems.

   Restrictions on Changing
       This tunable is dynamic (tuning will take effect immediately on the running system).

   What Other Tunables Should Be Changed at the Same Time as This One?
       None.

WARNINGS

       All HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases	of
       HP-UX.

       Installation  of  optional  kernel  software, from HP or other vendors, may cause changes to tunable parameter values.  After installation,
       some tunable parameters may no longer be at the default or recommended values.  For information about the effects of installation  on  tun-
       able  values,  consult  the documentation for the kernel software being installed.  For information about optional kernel software that was
       factory installed on your system, see at
