NAME

     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 superuser.

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.

     [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.

HISTORY

     The getfh() function first appeared in 4.4BSD.

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 lgetfh() system calls fail 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 255 characters, 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 translating 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.
