SYNOPSISIn sys/param.h In sys/mount.h Ft int Fn getfh const char *path fhandle_t *fhp Ft int Fn lgetfh const char *path fhandle_t *fhp
DESCRIPTIONThe Fn getfh system call returns a file handle for the specified file or directory in the file handle pointed to by Fa fhp . The Fn lgetfh system call is like Fn getfh except in the case where the named file is a symbolic link, in which case Fn lgetfh returns information about the link, while Fn getfh returns information about the file the link references. These system calls are restricted to the superuser.
