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 library routines described on this page
|
|
provide the application access to
|
|
the system network configuration database,
|
|
.Pa /etc/netconfig .
|
|
.Fn getnetconfig
|
|
returns a pointer to the
|
|
current entry in the
|
|
netconfig
|
|
database, formatted as a
|
|
.Ft "struct netconfig" .
|
|
Successive calls will return successive netconfig
|
|
entries in the netconfig database.
|
|
.Fn getnetconfig
|
|
can be used to search the entire netconfig
|
|
file.
|
|
.Fn getnetconfig
|
|
returns
|
|
.Dv NULL
|
|
at the end of the file.
|
|
.Fa handlep
|
|
is the handle obtained through
|
|
.Fn setnetconfig .
|
|
.Pp
|
|
A call to
|
|
.Fn setnetconfig
|
|
has the effect of
|
|
.Dq binding
|
|
to or
|
|
.Dq rewinding
|
|
the netconfig database.
|
|
.Fn setnetconfig
|
|
must be called before the first call to
|
|
.Fn getnetconfig
|
|
and may be called at any other time.
|
|
.Fn setnetconfig
|
|
need not be called before a call to
|
|
.Fn getnetconfigent .
|
|
.Fn setnetconfig
|
|
returns a unique handle to be used by
|
|
.Fn getnetconfig .
|
|
.Pp
|
|
.Fn endnetconfig
|
|
should be called when processing is complete to release resources for reuse.
|
|
.Fa handlep
|
|
is the handle obtained through
|
|
.Fn setnetconfig .
|
|
Programmers should be aware, however, that the last call to
|
|
.Fn endnetconfig
|
|
frees all memory allocated by
|
|
.Fn getnetconfig
|
|
for the
|
|
.Ft "struct netconfig"
|
|
data structure.
|
|
.Fn endnetconfig
|
|
may not be called before
|
|
.Fn setnetconfig .
|
|
.Pp
|
|
.Fn getnetconfigent
|
|
returns a pointer
|
|
to the netconfig structure corresponding
|
|
to
|
|
.Fa netid .
|
|
It returns
|
|
.Dv NULL
|
|
if
|
|
.Fa netid
|
|
is invalid
|
|
(that is, does not name an entry in the netconfig database).
|
|
.Pp
|
|
.Fn freenetconfigent
|
|
frees the netconfig structure pointed to by
|
|
.Fa netconfigp
|
|
(previously returned by
|
|
.Fn getnetconfigent ) .
|
|
.Pp
|
|
.Fn nc_perror
|
|
prints a message to the standard error indicating why any of the
|
|
above routines failed.
|
|
The message is prepended with the string
|
|
.Fa msg
|
|
and a colon.
|
|
A newline character is appended at the end of the message.
|
|
.Pp
|
|
.Fn nc_sperror
|
|
is similar to
|
|
.Fn nc_perror
|
|
but instead of sending the message
|
|
to the standard error, will return a pointer to a string that
|
|
contains the error message.
|
|
.Pp
|
|
.Fn nc_perror
|
|
and
|
|
.Fn nc_sperror
|
|
can also be used with the
|
|
.Ev NETPATH
|
|
access routines defined in
|
|
.Xr getnetpath 3 .
|
|
.Sh RETURN VALUES
|
|
.Fn setnetconfig
|
|
returns a unique handle to be used by
|
|
.Fn getnetconfig .
|
|
In the case of an error,
|
|
.Fn setnetconfig
|
|
returns
|
|
.Dv NULL
|
|
and
|
|
.Fn nc_perror
|
|
or
|
|
.Fn nc_sperror
|
|
can be used to print the reason for failure.
|
|
.Pp
|
|
.Fn getnetconfig
|
|
returns a pointer to the current entry in the netconfig
|
|
database, formatted as a
|
|
.Ft "struct netconfig" .
|
|
.Fn getnetconfig
|
|
returns
|
|
.Dv NULL
|
|
at the end of the file, or upon failure.
|
|
.Pp
|
|
.Fn endnetconfig
|
|
returns 0 on success and \-1 on failure
|
|
(for example, if
|
|
.Fn setnetconfig
|
|
was not called previously).
|
|
.Pp
|
|
On success,
|
|
.Fn getnetconfigent
|
|
returns a pointer to the
|
|
.Ft "struct netconfig"
|
|
structure corresponding to
|
|
.Fa netid ;
|
|
otherwise it returns
|
|
.Dv NULL .
|
|
.Pp
|
|
.Fn nc_sperror
|
|
returns a pointer to a buffer which contains the error message string.
|
|
This buffer is overwritten on each call.
|
|
In multithreaded applications, this buffer is
|
|
implemented as thread-specific data.
