</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine returns the nfs driver number allocated by iosDrvInstall during
the nfs driver initialization. If the nfs driver has yet to be initialized,
or if initialization failed, nfsDrvNumGet will return ERROR.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
the nfs driver number or ERROR

</blockquote><h1>nfsMount(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong>nfsMount(&nbsp;)</strong> - mount an NFS file system</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS nfsMount
    (
    char * host,              /* name of remote host */
    char * fileSystem,        /* name of remote directory to mount */
    char * localName          /* local device name for remote dir (NULL = */
                              /* use fileSystem name) */ 
    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine mounts a remote file system.  It creates a
local device <i>localName</i> for a remote file system on a specified host.
The host must have already been added to the local host table with
<b><a href="./hostLib.html#hostAdd">hostAdd</a>(&nbsp;)</b>.  If <i>localName</i> is NULL, the local name will be the same as
the remote name.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
OK, or ERROR if the driver is not installed,
<i>host</i> is invalid, or memory is insufficient.

</blockquote><h1>nfsMountAll(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong>nfsMountAll(&nbsp;)</strong> - mount all file systems exported by a specified host</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS nfsMountAll
    (
    char * pHostName,         /* name of remote host */
    char * pClientName,       /* name of a client specified in access */
                              /* list, if any */ 
    BOOL   quietFlag          /* FALSE = print name of each mounted file */
                              /* system */ 
    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine mounts the file systems exported by the host <i>pHostName</i>
which are accessible by <i>pClientName</i>. A <i>pClientName</i> entry of NULL
will only mount file systems that are accessible by any client. 
The <b><a href="./nfsDrv.html#nfsMount">nfsMount</a>(&nbsp;)</b> routine is called to mount each file system. It creates
a local device for each mount that has the same name as the remote file
system.
<p>
If the <i>quietFlag</i> setting is FALSE, each file system is printed on
standard output after it is mounted successfully.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
OK, or ERROR if any mount fails.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine displays the device names and their associated NFS file systems.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS nfsUnmount

    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine unmounts file systems that were previously mounted via NFS.

</blockquote><h4>RETURNS</h4><blockquote><p>
OK, or ERROR if <i>localName</i> is not an NFS device or cannot
be mounted.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine fills the array <i>nfsDevlist</i> up to <i>listSize</i>, with handles to
NFS devices currently in the system.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
The number of entries filled in the <i>nfsDevList</i> array.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>STATUS nfsDevInfoGet
    (
    unsigned long  nfsDevHandle, /* NFS device handle */
    NFS_DEV_INFO * pnfsInfo      /* ptr to struct to hold config info */
    )
</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine accesses the NFS device specified in the parameter <i>nfsDevHandle</i>
and fills in the structure pointed to by <i>pnfsInfo</i>. The calling function 
should allocate memory for <i>pnfsInfo</i> and for the two character buffers,
<b>remFileSys</b> and <b>locFileSys</b>, that are part of <i>pnfsInfo</i>. These buffers 
should have a size of <b>nfsMaxPath</b>.
<p>
</blockquote><h4>RETURNS</h4><blockquote><p>
OK if <i>pnfsInfo</i> information is valid, otherwise ERROR.
