/* obj.c
 *
 * This file implements a generic object "class". All other classes can
 * use the service of this base class here to include auto-destruction and
 * other capabilities in a generic manner.
 *
 * As of 2008-02-29, I (rgerhards) am adding support for dynamically loadable
 * objects. In essence, each object will soon be available via its interface,
 * only. Before any object's code is accessed (including global static methods),
 * the caller needs to obtain an object interface. To do so, it needs to provide
 * the object name and the file where the object is expected to reside in. A
 * file may not be given, in which case the object is expected to reside in
 * the rsyslog core. The caller than receives an interface pointer which can
 * be utilized to access all the object's methods. This method enables rsyslog
 * to load library modules on demand. In order to keep overhead low, callers
 * should request object interface only once in the object Init function and
 * free them when they exit. The only exception is when a caller needs to
 * access an object only conditional, in which case a pointer to its interface
 * shall be aquired as need first arises but still be released only on exit
 * or when there definitely is no further need. The whole idea is to limit
 * the very performance-intense act of dynamically loading an objects library.
 * Of course, it is possible to violate this suggestion, but than you should
 * have very good reasoning to do so.
 *
 * Please note that there is one trick we need to do. Each object queries
 * the object interfaces and it does so via objUse(). objUse, however, is
 * part of the obj object's interface (implemented via the file you are
 * just reading). So in order to obtain a pointer to objUse, we need to
 * call it - obviously not possible. One solution would be that objUse is
 * hardcoded into all callers. That, however, would bring us into slight
 * trouble with actually dynamically loaded modules, as we should NOT
 * rely on the OS loader to resolve symbols back to the caller (this
 * is a feature not universally available and highly importable). Of course,
 * we can solve this with a pHostQueryEtryPoint() call. It still sounds
 * somewhat unnatural to call a regular interface function via a special
 * method. So what we do instead is define a special function called
 * objGetObjInterface() which delivers our own interface. That function
 * than will be defined global and be queriable via pHostQueryEtryPoint().
 * I agree, technically this is much the same, but from an architecture
 * point of view it looks cleaner (at least to me).
 * 
 * Please note that there is another egg-hen problem: we use a linked list,
 * which is provided by the linkedList object. However, we need to
 * initialize the linked list before we can provide the UseObj()
 * functionality. That, in turn, would probably be required by the 
 * linkedList object. So the solution is to use a backdoor just to
 * init the linked list and from then on use the usual interfaces.
