NAME
getfh -- get file handle
SYNOPSIS
#include <sys/types.h>

DESCRIPTION

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

Getfh() fails if one or more of the following are true:
[ENOTDIR] A component of the path prefix of path is not a directory.
[ENAMETOOLONG] The length of a component of path exceeds {NAME_MAX} characters, or the length of
path exceeds {PATH_MAX} characters.
[ENOENT] The file referred to by path does not exist.
[EPERM] The caller is not the super-user.
[EACCES] Search permission is denied for a component of the path prefix of path.
[ELOOP] Too many symbolic links were encountered in translating path.
