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 It has been replaced by a set of files in the nfsd filesystem; see nfsd(7).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