@defvr Macro _REENTRANT,_THREAD_SAFE
If you define this macro, reentrant versions of several functions get
declared. Some of the functions is specified in POSIX.1c but many others
are only available on a few other systems or are unique to GNU libc.
The problem is that the standardization of the thread safe C library
interface still is behind.
Unlike on some other systems no special version of the C library must be
used for linking. There is only one version but while compiling this
it must have been specified to compile as thread safe.

@subsection Netgroup Data
@cindex{Netgroup}
Sometimes it is useful group users according to other criterias like the
ones used in the @xref{Group Database}. E.g., it is useful to associate
a certain group of users with a certain machine. On the other hand
grouping of host names is not supported so far.
In Sun Microsystems SunOS appeared a new kind of database, the netgroup
database. It allows to group hosts, users, and domain freely, giving
them individual names. More concrete: a netgroup is a list of triples
consisting of a host name, a user name, and a domain name, where any of
the entries can be a wildcard entry, matching all inputs. A last
possibility is that names of other netgroups can also be given in the
list specifying a netgroup. So one can construct arbitrary hierachies
without loops.
Sun's implementation allows netgroups only for the @code{nis} or
@code{nisplus} service @pxref{Services in the NSS configuration}. The
implementation in the GNU C library has no such restriction. An entry
in either of the input services must have the following form:
@smallexample
@var{groupname} ( @var{groupname} | @code{(}@var{hostname}@code{,}@var{username}@code{,}@code{domainname}@code{)} )+
@end smallexample
Any of the fields in the triple can be empty which means anything
matches. While describing te functions we will see that the opposite
case is useful as well. I.e., there shall be entries which will not
match any input. For entries like a name consisting of the single
character @code{-} shall be used.
@node Lookup Netgroup, Netgroup Membership, Netgroup Data, Netgroup Database
@subsection Looking up one Netgroup
The lookup functions for netgroups are a bit different to all other
system database handling functions. Since a single netgroup can contain
many entries a two-step process is needed. First a single netgroup is
selected and then one can iterate over all entries in this netgroup.
These functions are declared in @file{netdb.h}.
@comment netdb.h
@deftypefun int setnetgrent (const char *@var{netgroup})
A call to this function initializes the internal state of the library to
allow following calls of the @code{getnetgrent} iterate over all entries
in the netgroup with name @var{netgroup}.
When the call is successful (i.e., when a netgroup with this name exist)
the return value is @code{1}. When the return value is @code{0} no
netgroup of this name is known or some other error occured.
@end deftypefun
It is important to remember that there is only one single state for
iterating the netgroups. Even if the programmer uses the
@code{getnetgrent_r} function the result is not really reentrant since
always only one single netgroup at a time can be processed. If the
program needs to process more than one netgroup simultaneously she
must protect this by using external locking. This problem was
introduced in the original netgroups implementation in SunOS and since
we must stay compatible it is not possible to change this.
Some other functions also use the netgroups state. Currently these are
the @code{innetgr} function and parts of the implementation of the
@code{compat} service part of the NSS implementation.
@comment netdb.h
@deftypefun int getnetgrent (char **@var{hostp}, char **@var{userp}, char **@var{domainp})
This function returns the next unprocessed entry of the currently
selected netgroup. The string pointers, which addresses are passed in
the arguments @var{hostp}, @var{userp}, and @var{domainp}, will contain
after a successful call pointers to appropriate strings. If the string
in the next entry is empty the pointer has the value @code{NULL}.
The returned string pointers are only valid unless no of the netgroup
related functions are called.
The return value is @code{1} if the next entry was successfully read. A
value of @code{0} means no further entry exist or internal errors occured.
@end deftypefun
@comment netdb.h
@deftypefun int getnetgrent_r (char **@var{hostp}, char **@var{userp}, char **@var{domainp}, char *@var{buffer}, int @var{buflen})
This function is similar to @code{getnetgrent} with only one exception:
the strings the three string pointers @var{hostp}, @var{userp}, and
@var{domainp} point to, are placed in the buffer of @var{buflen} bytes
starting at @var{buffer}. This means the returned values are valid
even after other netgroup related functions are called.
The return value is @code{1} if the next entry was successfully read and
the buffer contains enough room to place the strings in it. @code{0} is
returned in case no more entries are found, the buffer is too small, or
internal errors occured.
This function is a GNU extension. The original implementation in the
SunOS libc does not provide this function.
@end deftypefun
@comment netdb.h
@deftypefun void endnetgrent (void)
This function free all buffers which were allocated to process the last
selected netgroup. As a result all string pointers returned by calls
to @code{getnetgrent} are invalid afterwards.
@end deftypefun
@node Netgroup Membership, , Lookup Netgroup, Netgroup Database
@subsection Testing for Netgroup Membership
It is often not necessary to scan the whole netgroup since often the
only interesting question is whether a given entry is part of the
selected netgroup.
@comment netdb.h
@deftypefun int innetgr (const char *@var{netgroup}, const char *@var{host}, const char *@var{user}, const char *@var{domain})
This function tests whether the triple specified by the parameters
@var{hostp}, @var{userp}, and @var{domainp} is part of the netgroup
@var{netgroup}. Using this function has the advantage that
@enumerate
@item
no other netgroup function can use the global netgroup state since
internal locking is used and
@item
the function is implemented more efficiently than successive calls
to the other @code{set}/@code{get}/@code{endnetgrent} functions.
@end enumerate
Any of the pointers @var{hostp}, @var{userp}, and @var{domainp} can be
@code{NULL} which means any value is excepted in this position. This is
also true for the name @code{-} which should not match any other string
otherwise.
The return value is @code{1} if an entry matching the given triple is
found in the netgroup. The return value is @code{0} is the netgroup
itself is not found, the netgroup does not contain the triple or
internal errors occured.
