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.

/*
 * 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;
};
