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]: An I/O error occurred while reading from or writing to the file system.
