NFSSERVCTL(2) Linux Programmer's Manual NFSSERVCTL(2)

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  It has been
     replaced by a set of files in the nfsd filesystem; see nfsd(7).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 {
                 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; };

RETURN VALUE

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

CONFORMING TO

     This call is Linux-specific.
