These system calls provide a means to access a file given the file handle
fhp.
As this method bypasses directory access restrictions, these calls are
restricted to the superuser.
The
fhopen()
system call
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
argument
is specified by
or'ing
together the flags used for the
open(2)
system call.
All said flags are valid except for
O_CREAT.
The
fhstat()
and
fhstatfs()
system calls
provide the functionality of the
fstat(2)
and
fstatfs(2)
calls except that they return information for the file referred to by
fhp
rather than an open file.
