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 lgetfh() 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.
