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


#include <errno.h> #include <time.h> #include <nfs/nfs.h> #include <rpc/rpc.h> int getfh(char *path, fhandle_t *fhp);


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.


getfh() returns the following values:


Successful completion.


Failure. errno is set to indicate the error.


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


Invalid argument, or the file or directory has not been exported by exportfs (see exportfs(1M)).


File or directory specified by path does not exist.


The effective user ID is not superuser.


The file or directory specified by path is a remote file or directory.


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


getfh() was developed by Sun Microsystems, Inc.
