getfh, lgetfh -- get file handle
Standard C Library (libc, -lc)
getfh(const char *path, fhandle_t *fhp);
lgetfh(const char *path, fhandle_t *fhp);
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.
Upon successful completion, the value 0 is returned; otherwise the
value -1 is returned and the global variable errno is set to indicate the
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
[ENAMETOOLONG] The length of a component of path exceeds 255
characters, or the length of path exceeds 1023
[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
[EFAULT] The fhp argument points to an invalid address.
[EIO] An I/O error occurred while reading from or writing to
the file system.
The getfh() system call first appeared in 4.4BSD.
