GETFH(2) System Calls Manual GETFH(2)

getfhget file handle

#include <sys/types.h>
#include <sys/mount.h>

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

() 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 super-user and is used by an NFS server's nfsd(8) daemon to obtain file handles used in NFS MOUNT service replies.

Upon successful completion, a value of 0 is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.

getfh() fails if one or more of the following are true:

A component of the path prefix of path is not a directory.
The length of a component of path exceeds {NAME_MAX} characters, or the length of path exceeds {PATH_MAX} characters.
The file referred to by path does not exist.
The caller is not the super-user.
Search permission is denied for a component of the path prefix of path.
Too many symbolic links were encountered in translating path.
Fhp points to an invalid address.
An I/O error occurred while reading from or writing to the file system.


The getfh() function first appeared in 4.4BSD.
