NAME

       async_daemon - Creates a local NFS asynchronous I/O server

SYNOPSIS

       async_daemon(
	       unsigned long iod_num,
	       unsigned long magic);

PARAMETERS

       Specifies the number of I/O threads to run.  For Tru64 UNIX, this is 950410.  If a different value is used, seven NFS I/O threads are run.

DESCRIPTION

       The  use  of  the async_daemon() function is not supported in customer applications, and the interface is subject to change without notice.
       It is intended for use solely by nfsiod(8).

       The async_daemon() function starts iod_num NFS I/O kernel threads that are used to improve NFS I/O performance.	 This  function  does  not
       return to the caller, but remains in the kernel to provide additional support for NFS over TCP.

RETURN VALUES

       The  async_daemon  function  has no successful return.  In fact, it frees the text and data segments associated with the calling program so
       there is nothing to return to.  When interrupted by a KILL signal, the I/O threads are terminated and the process exits.  If the async_dae-
       mon function encounters errors, , -1 is returned and errno is set to indicate the error.

ERRORS

       If the async_daemon() function fails, errno may be set to the following value: The async_daemon function has already been called by another
       process.  The caller is not the superuser.  More than 64 I/O threads were requested.  The kernel memory allocator has no memory.
