NAME [Toc] [Back]
getfh() - return file handle for file on remote node
SYNOPSIS [Toc] [Back]
#include <errno.h>
#include <time.h>
#include <nfs/nfs.h>
#include <rpc/rpc.h>
int getfh(char *path, fhandle_t *fhp);
DESCRIPTION [Toc] [Back]
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 [Toc] [Back]
getfh() returns the following values:
0 Successful completion.
-1 Failure. errno is set to indicate the error.
ERRORS [Toc] [Back]
If 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 [Toc] [Back]
This call should be used only by HP-supplied commands and is not
recommended for use by non-HP-supplied programs.
