nfsservctl(2) System Calls Manual nfsservctl(2)

NAME

nfsservctl - syscall interface to kernel nfs daemon

LIBRARY

Standard C library (libc, -lc)

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 It has been replaced by a set of files in the nfsd filesystem; see nfsd(7).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(8))
(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 to indicate the error.

VERSIONS

This system call was removed in Linux 3.1. Library support was removed in glibc 2.28.

STANDARDS

This call is Linux-specific.
