NAME
nfsservctl - syscall interface to kernel nfs daemon
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
bash
#include <linux/nfsd/syscall.h>bash
long nfsservctl(int \ncmd\n, struct nfsctl_arg *\nargp\n,\n
\n union nfsctl_res *\nresp\n);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 It has been replaced by a set of files in the nfsd filesystem; see nfsd(7).
bash
