associated changes that had to happen to make this possible as well as
bugs fixed along the way.
Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

.Sh DESCRIPTION
|
|
The routines described in this page provide the application access to the system
|
|
network configuration database,
|
|
.Pa /etc/netconfig ,
|
|
as it is
|
|
.Dq filtered
|
|
by the
|
|
.Ev NETPATH
|
|
environment variable (see
|
|
.Xr environ 5 ) .
|
|
See
|
|
.Xr getnetconfig 3
|
|
for other routines that also access the
|
|
network configuration database directly.
|
|
The
|
|
.Ev NETPATH
|
|
variable is a list of colon-separated network identifiers.
|
|
.Pp
|
|
.Fn getnetpath
|
|
returns a pointer to the
|
|
netconfig database entry corresponding to the first valid
|
|
.Ev NETPATH
|
|
component.
|
|
The netconfig entry is formatted as a
|
|
.Ft "struct netconfig" .
|
|
On each subsequent call,
|
|
.Fn getnetpath
|
|
returns a pointer to the netconfig entry that corresponds to the next
|
|
valid
|
|
.Ev NETPATH
|
|
component.
|
|
.Fn getnetpath
|
|
can thus be used to search the netconfig database for all networks
|
|
included in the
|
|
.Ev NETPATH
|
|
variable.
|
|
When
|
|
.Ev NETPATH
|
|
has been exhausted,
|
|
.Fn getnetpath
|
|
returns
|
|
.Dv NULL .
|
|
.Pp
|
|
A call to
|
|
.Fn setnetpath
|
|
.Dq binds
|
|
to or
|
|
.Dq rewinds
|
|
.Ev NETPATH .
|
|
.Fn setnetpath
|
|
must be called before the first call to
|
|
.Fn getnetpath
|
|
and may be called at any other time.
|
|
It returns a handle that is used by
|
|
.Fn getnetpath .
|
|
.Pp
|
|
.Fn getnetpath
|
|
silently ignores invalid
|
|
.Ev NETPATH
|
|
components.
|
|
A
|
|
.Ev NETPATH
|
|
component is invalid if there is no corresponding
|
|
entry in the netconfig database.
|
|
.Pp
|
|
If the
|
|
.Ev NETPATH
|
|
variable is unset,
|
|
.Fn getnetpath
|
|
behaves as if
|
|
.Ev NETPATH
|
|
were set to the sequence of
|
|
.Dq default
|
|
or
|
|
.Dq visible
|
|
networks in the netconfig database, in the
|
|
order in which they are listed.
|
|
.\"This proviso holds also for this
|
|
.\"whole manpage.
|
|
.Pp
|
|
.Fn endnetpath
|
|
may be called to
|
|
.Dq unbind
|
|
from
|
|
.Ev NETPATH
|
|
when processing is complete, releasing resources for reuse.
|
|
Programmers should be aware, however, that
|
|
.Fn endnetpath
|
|
frees all memory allocated by
|
|
.Fn getnetpath
|
|
for the struct netconfig data structure.
|
|
.Sh RETURN VALUES
|
|
.Fn setnetpath
|
|
returns a handle that is used by
|
|
.Fn getnetpath .
|
|
In case of an error,
|
|
.Fn setnetpath
|
|
returns
|
|
.Dv NULL .
|
|
.Pp
|
|
.Fn endnetpath
|
|
returns 0 on success and \-1 on failure
|
|
(for example, if
|
|
.Fn setnetpath
|
|
was not called previously).
|
|
.Fn nc_perror
|
|
or
|
|
.Fn nc_sperror
|
|
can be used to print out the reason for failure.
|
|
See
|
|
.Xr getnetconfig 3 .
|
|
.Pp
|
|
When first called,
|
|
.Fn getnetpath
|
|
returns a pointer to the netconfig database entry corresponding to the first
|
|
valid
|
|
.Ev NETPATH
|
|
component.
|
|
When
|
|
.Ev NETPATH
|
|
has been exhausted,
|
|
.Fn getnetpath
|
|
returns
|
|
.Dv NULL .
