       exportfs - exports an NFS file system

       #include <sys/mount.h>
       exportfs(name, rootuid, exflags)
       char *name;
       int rootuid, exflags;

       The  system  call  allows the specified local file system to be mounted
       remotely by an NFS client.  This system call  is	 usually  called  from
       Security	 on  the  exported file systems can be improved by setting the
       root mapped user ID, rootuid, and two mount  structure  flags,  exflags
       for the local file system, name.

       The  name  argument is a pointer to a null-terminated string containing
       the path name of the file system being exported.

       The rootuid argument is used to set the user ID that root maps to.   By
       default, root maps to user id -2.

       The exflags argument contains the flags that are to be set in the mount
       structure corresponding to name.	 The following flags are the only pos‐
       sible flags accepted by
       #define M_NOFH	       0x1000	       /* no fhandle flag */
       #define M_EXRONLY       0x2000	       /* export read-only */

       Setting	the  M_NOFH  flag  does not allow access to the fhandle of the
       file system's root gnode.  The M_EXRONLY flag exports a filesystem read

       The  system  call  returns a value of 0 upon successful completion of a
       operation, and -1 upon failure.

       [EPERM]	      Not superuser.

       [EIO]	      Not enough memory in the system to service the request.

       [EFAULT]	      Bad address or bad length of name.

       [ENOENT]	      The name cannot be found.
