NAME
       nfsservctl - syscall interface to kernel nfs daemon

SYNOPSIS
       #include <linux/nfsd/syscall.h>

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

DESCRIPTION
       /*
        * 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 file system. */
       #define NFSCTL_UNEXPORT         4       /* unexport a file system. */
       #define NFSCTL_UGIDUPDATE       5       /* update a client's uid/gid map. */
       #define NFSCTL_GETFH            6       /* get an fh (used by mountd) */

       struct nfsctl_arg {
               int                     ca_version;     /* safeguard */
               union {
                       struct nfsctl_svc       u_svc;
                       struct nfsctl_client    u_client;
                       struct nfsctl_export    u_export;
                       struct nfsctl_uidmap    u_umap;
                       struct nfsctl_fhparm    u_getfh;
                       unsigned int            u_debug;
               } u;
       }

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