getfh(2) getfh(2)

NAME

getfh() - return ﬁle handle for ﬁle on remote node

SYNOPSIS

#include <errno.h>

#include <time.h>

#include <nfs/nfs.h>

#include <rpc/rpc.h>

int getfh(char *path, fhandle_t *fhp);

DESCRIPTION

The getfh() system call returns a ﬁle handle in the

struct pointed to by fhp for the ﬁle pointed to by

path . This information is used to perform an NFS mount for a remote node.

getfh() is executed on

the remote node; results are passed back to the program doing the NFS mount. The caller should never

examine the ﬁle handle contents. The ﬁle handle only identiﬁes a ﬁle to the node that produced the ﬁle

handle. (The term "ﬁle handle" refers to an NFS concept.)

The effective user ID of the calling process must be superuser.

RETURN VALUE

getfh() returns the following values:

0 Successful completion.

-1 Failure. errno is set to indicate the error.

ERRORS

getfh() fails, errno is set to one of the following values.

[EINVAL] Invalid argument, or the ﬁle or directory has not been exported by

exportfs (see

exportfs (1M)).

[ENOENT] File or directory speciﬁed by path does not exist.

[EPERM] The effective user ID is not superuser.

[EREMOTE] The ﬁle or directory speciﬁed by path is a remote ﬁle or directory.

WARNINGS

This call should be used only by HP-supplied commands and is not recommended for use by non-HP-

supplied programs.
