getfh(2)

NAME

getfh, lgetfh - get file handle

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <sys/param.h>
#include <sys/mount.h>
int
getfh(const char *path, fhandlet_*fhp);
int
lgetfh(const char *path, fhandlet_*fhp);

DESCRIPTION

The getfh() system call returns a file handle for the speci

fied file or
directory in the file handle pointed to by fhp. The

lgetfh() system call
is like getfh() except in the case where the named file is a

symbolic
link, in which case lgetfh() returns information about the

link, while
getfh() returns information about the file the link refer

ences. These
system calls are restricted to the superuser.

RETURN VALUES

The function returns the value 0 if successful; otherwise

the value -1 is
returned and the global variable errno is set to indicate

the error.

ERRORS

The getfh() and lgetfgh() system calls fail if one or more

of the following are true:

[ENOTDIR] A component of the path prefix of path is

not a direc

tory.

[ENAMETOOLONG] The length of a component of path exceeds

255 charac

ters, or the length of path exceeds 1023

characters.

[ENOENT] The file referred to by path does not ex

[EACCES] Search permission is denied for a compo

[ELOOP] Too many symbolic links were encountered

[EFAULT] The fhp argument points to an invalid ad

[EIO] An I/O error occurred while reading from

or writing to

the file system.
