Name
       getnetgrent, setnetgrent, endnetgrent, innetgr - get network group entry

Syntax
       innetgr(netgroup, machine, user, domain)
       char *netgroup, *machine, *user, *domain;
       setnetgrent(netgroup)
       char *netgroup
       endnetgrent()
       getnetgrent(machinep, userp, domainp)
       char **machinep, **userp, **domainp;

Description
       The  routine accesses the file and checks to see if the specified input parameters match an entry in the file.  The routine returns 1 if it
       matches an entry, or 0 if it does not.  Any of the three strings; machine, user, or domain can be NULL, which signifies any string in  that
       position is valid.

       The  routine  returns  the  next  member of a network group.  After the call, will contain a pointer to a string containing the name of the
       machine part of the network group member, and similarly for userp and domainp.  If machinep,  userp  or	domainp  is  returned  as  a  NULL
       pointer,  it signifies any string is valid.  The routine allocates space for the name by using the routine.  This space is released when an
       call is made.  The routine returns 1 if it succeeds in obtaining another member of the network group, or 0 if it reaches  the  end  of  the
       group.

       The  routine  establishes  the network group from which will obtain members, and also restarts calls to from the beginning of the list.	If
       the previous call was to a different network group, an call is implied.

       The routine releases the space allocated during the calls.
