getfh(2).
As this method bypasses directory access restrictions, these calls are
restricted to the superuser.
fhopen()
opens the file referenced by
fhp
for reading and/or writing as specified by the argument
flags
and returns the file descriptor to the calling process.
The
flags
are specified by
or'ing
together the flags used for the
open(2)
call.
All said flags are valid except for
O_CREAT
.
fhstat(),
fhstatvfs(

and
fhstatvfs1(

provide the functionality of the
fstat(2),
fstatvfs(2),
and
fstatvfs1(2)
calls except that they return information for the file referred to by
fhp
rather than an open file.
