NAME

       nfsservctl - syscall interface to kernel nfs daemon

SYNOPSIS

       #include <linux/nfsd/syscall.h>

       long nfsservctl(int cmd, struct nfsctl_arg *argp,
		       union nfsctl_res *resp);

DESCRIPTION

       Note: Since Linux 3.1, this system call no longer exists.  It has been replaced by a set of files in the nfsd filesystem; see nfsd(7).

	    * These are the commands understood by nfsctl().
	    */
	   #define NFSCTL_SVC	     0	/* This is a server process. */
	   #define NFSCTL_ADDCLIENT  1	/* Add an NFS client. */
	   #define NFSCTL_DELCLIENT  2	/* Remove an NFS client. */
	   #define NFSCTL_EXPORT     3	/* Export a filesystem. */
	   #define NFSCTL_UNEXPORT   4	/* Unexport a filesystem. */
	   #define NFSCTL_UGIDUPDATE 5	/* Update a client's UID/GID map
					   (only in Linux 2.4.x and earlier). */
	   #define NFSCTL_GETFH      6	/* Get a file handle (used by mountd)
					   (only in Linux 2.4.x and earlier). */

	   struct nfsctl_arg {
	       int			 ca_version;	 /* safeguard */
	       union {

	   }

	   union nfsctl_res {
		   struct knfs_fh	   cr_getfh;
		   unsigned int 	   cr_debug;
	   };

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

CONFORMING TO

       This call is Linux-specific.
