GETFH(2) BSD System Calls Manual 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, fhandle_t *fhp);
int
lgetfh(const char *path, fhandle_t *fhp);
DESCRIPTION
The getfh() system call returns a file handle for the specified 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 references. These
system calls are restricted to the superuser.
RETURN VALUES
Upon successful completion, the value 0 is returned; 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 follow‐
ing 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 exist.
[EACCES] Search permission is denied for a component of the
path prefix of path.
[ELOOP] Too many symbolic links were encountered in translat‐
ing path.
[EFAULT] The fhp argument points to an invalid address.
[EIO] An I/O error occurred while reading from or writing to
the file system.
HISTORY
The getfh() system call first appeared in 4.4BSD.
