NAME
       nfsservctl - syscall interface to kernel nfs daemon

SYNOPSIS
       #include 

       long nfsservctl(int cmd, struct nfsctlarg *argp,
                       union nfsctlres *resp);

DESCRIPTION
       Note: Since Linux 3.1, this system call no longer exists.

       /*
        * These are the commands understood by nfsctl().
        */
       #define NFSCTLSVC          0    /* This is a server process. */
       #define NFSCTLADDCLIENT    1    /* Add an NFS client. */
       #define NFSCTLDELCLIENT    2    /* Remove an NFS client. */
       #define NFSCTLEXPORT       3    /* export a file system. */
       #define NFSCTLUNEXPORT     4    /* unexport a file system. */
       #define NFSCTLUGIDUPDATE   5    /* update a client's UID/GID map. */
       #define NFSCTLGETFH        6    /* get an fh (used by mountd) */

       struct nfsctlarg {
           int                       caversion;     /* safeguard */
           union {
               struct nfsctlsvc     usvc;
               struct nfsctlclient  uclient;
               struct nfsctlexport  uexport;
               struct nfsctluidmap  uumap;
               struct nfsctlfhparm  ugetfh;
               unsigned int          udebug;
           } u;
       }

       union nfsctlres {
               struct knfsfh          crgetfh;
               unsigned int            crdebug;
       };
