getfh — get file handle

SYNOPSIS

#include <sys/types.h>
#include <sys/mount.h>

int
getfh(const char *path, fhandle_t *fhp);

DESCRIPTION

getfh() returns a file handle for the specified file or directory in the file handle pointed to by fhp. This system call is restricted to the super-user and is used by an NFS server's nfsd(8) daemon to obtain file handles used in NFS MOUNT service replies.

RETURN VALUES

Upon successful completion, a value of 0 is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.

ERRORS

getfh() fails if one or more of the following are true:

[ENOTDIR]

A component of the path prefix of path is not a directory.

[ENAMETOOLONG]

The length of a component of path exceeds {NAME_MAX} characters, or the length of path exceeds {PATH_MAX} characters.

[ENOENT]

The file referred to by path does not exist.

[EPERM]

The caller is not the super-user.

[EACCES]

Search permission is denied for a component of the path prefix of path.

[ELOOP]

Too many symbolic links were encountered in translating path.

[EFAULT]

Fhp points to an invalid address.

[EIO]
