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) */

         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;
