NAME
       asyncdaemon - start a BIOD server for asynchronous I/O requests

SYNOPSIS
       int  asyncdaemon ()

DESCRIPTION
       This system call does not normally return; instead, the process
       becomes a system process that asynchronously transfers blocks between
       memory and I/O devices.  Normally, some number of BIOD processes are
       created when the system is brought to init level 1 or higher.

ACCESS CONTROL
       Must have appropriate privilege to execute this system call.  On a
       generic DG/UX system, appropriate privilege is granted by having an
       effective UID of 0 (root).  See the appropriateprivilege(5) man page
       for more information.

       On a system with DG/UX information security, appropriate privilege is
       granted by having one or more specific capabilities enabled in the
       effective capability set of the user.  See capdefaults(5) for the
       default capabilities for this system call.

RETURN VALUE
       -1     An error occurred.  errno is set to indicate the error.

DIAGNOSTICS
       Errno may be set to one of the following error codes:

       EPERM     The process has no permission to make the call.

       EINTR     The process was terminated by a signal.
