+# win16_3.11.mk -- Make configuration for Win16
+#
+# This file configures gmake to build the Win16 variant of
+# NSPR 2.0. This file has the function of two files commonly
+# used on other platforms, for example: winnt.mk and
+# winnt4.0.mk. ... The packaging is easier and there is only
+# one variant of the Win16 target.
+# 
+# Win16 is built using the Watcom C/C++ version 11.0
+# compiler. You gotta set up the compiler first. Follow the
+# directions in the manual (Ha! ... really, its not a
+# problem). The Watcom compiler depends on a few environment
+# variables; these environment variables define where the
+# compiler components are installed; they must be set before
+# running the make.
+# 
+# Notes:
+# OS_CFLAGS is the command line options for the compiler when
+#   building the .DLL object files.
+# OS_EXE_CFLAGS is the command line options for the compiler
+#   when building the .EXE object files; this is for the test
+#   programs.
+# the macro OS_CFLAGS is set to OS_EXE_CFLAGS inside of the
+#   makefile for the pr/tests directory. ... Hack.
+# 
+# USE_WATCOM_DEBUG_DATA environment variable causes the
+#   watcom compiler flag to be set to -hw (otherwise
+#   it is set to -hc (codeview debug data)) for debug builds.

+/**********************************************************************
+NSPL Events
+
+Defining Events
+---------------
+
+Events are essentially structures that represent argument lists for a
+function that will run on another thread. All event structures you
+define must include a PLEvent struct as their first field:
+
+    typedef struct MyEventType {
+        PLEvent	e;
+		// arguments follow...
+        int	x;
+		char*	y;
+    } MyEventType;
+
+It is also essential that you establish a model of ownership for each
+argument passed in an event record, i.e. whether particular arguments
+will be deleted by the event destruction callback, or whether they
+only loaned to the event handler callback, and guaranteed to persist
+until the time at which the handler is called.
+
+Sending Events
+--------------
+
+Events are initialized by PL_InitEvent and can be sent via
+PL_PostEvent or PL_PostSynchronousEvent. Events can also have an
+owner. The owner of an event can revoke all the events in a given
+event-queue by calling PL_RevokeEvents. An owner might want
+to do this if, for instance, it is being destroyed, and handling the
+events after the owner's destruction would cause an error (e.g. an
+MWContext).
+
+Since the act of initializing and posting an event must be coordinated
+with it's possible revocation, it is essential that the event-queue's
+monitor be entered surrounding the code that constructs, initializes
+and posts the event:
+
+    void postMyEvent(MyOwner* owner, int x, char* y)
+    {
+		MyEventType* event;
+
+		PL_ENTER_EVENT_QUEUE_MONITOR(myQueue);
+
+		// construct
+		event = PR_NEW(MyEventType);
+		if (event == NULL) goto done;
+
+		// initialize
+		PL_InitEvent(event, owner,
+					 (PLHandleEventProc)handleMyEvent,
+					 (PLDestroyEventProc)destroyMyEvent);
+		event->x = x;
+		event->y = strdup(y);
+
+		// post
+		PL_PostEvent(myQueue, &event->e);
+
+      done:
+		PL_EXIT_EVENT_QUEUE_MONITOR(myQueue);
+    }
+
+If you don't call PL_InitEvent and PL_PostEvent within the
+event-queue's monitor, you'll get a big red assert. 
+
+Handling Events
+---------------
+
+To handle an event you must write a callback that is passed the event
+record you defined containing the event's arguments:
+
+    void* handleMyEvent(MyEventType* event)
+    {
+		doit(event->x, event->y);
+		return NULL;	// you could return a value for a sync event
+    }
+
+Similarly for the destruction callback:
+
+    void destroyMyEvent(MyEventType* event)
+    {
+		free(event->y);	// created by strdup
+		free(event);
+    }
+
+Processing Events in Your Event Loop
+------------------------------------
+
+If your main loop only processes events delivered to the event queue,
+things are rather simple. You just get the next event (which may
+block), and then handle it:
+
+    while (1) {
+		event = PL_GetEvent(myQueue);
+		PL_HandleEvent(event);
+    }
+
+However, if other things must be waited on, you'll need to obtain a
+file-descriptor that represents your event queue, and hand it to select:
+
+    fd = PL_GetEventQueueSelectFD(myQueue);
+    ...add fd to select set...
+    while (select(...)) {
+		if (...fd...) {
+		    PL_ProcessPendingEvents(myQueue);
+		}
+		...
+    }
+
+Of course, with Motif and Windows it's more complicated than that, and
+on Mac it's completely different, but you get the picture.
+
+Revoking Events
+---------------
+If at any time an owner of events is about to be destroyed, you must
+take steps to ensure that no one tries to use the event queue after
+the owner is gone (or a crash may result). You can do this by either
+processing all the events in the queue before destroying the owner:
+
+    {
+		...
+		PL_ENTER_EVENT_QUEUE_MONITOR(myQueue);
+		PL_ProcessPendingEvents(myQueue);
+		DestroyMyOwner(owner);
+		PL_EXIT_EVENT_QUEUE_MONITOR(myQueue);
+		...
+    }
+
+or by revoking the events that are in the queue for that owner. This
+removes them from the queue and calls their destruction callback:
+
+    {
+		...
+		PL_ENTER_EVENT_QUEUE_MONITOR(myQueue);
+		PL_RevokeEvents(myQueue, owner);
+		DestroyMyOwner(owner);
+		PL_EXIT_EVENT_QUEUE_MONITOR(myQueue);
+		...
+    }
+
+In either case it is essential that you be in the event-queue's monitor
+to ensure that all events are removed from the queue for that owner, 
+and to ensure that no more events will be delivered for that owner.

+NSPR 2.0 libc functions
+-----------------------
+
+Last edited: AOF 04 March 1997
+
+This directory contains various libc-types of functions. All functions in
+this directory are platform independent, thread friendly (both safe and
+efficient). They are contributed from various sources, though the contri-
+butions are monitored by the NSPR group (mailto:freier).
+
+All API items exported by these functions will contain the same three
+character prefix, "PL_" (Portable Library). Internal function names
+that are not exported (static) are of little concern, though some caution
+must be used on those elements that are 'extern' but not really intended
+to be part of the API. Those should all have a prefix of "_PL_" (is that
+legal?).
+
+The responsibility for contributions in this area are distributed among
+all interested parties.

+NSPR 2.0 libc functions
+-----------------------
+
+Last edited: AOF 04 March 1997
+
+This directory contains various libc-types of functions. All functions in
+this directory are platform independent, thread friendly (both safe and
+efficient). They are contributed from various sources, though the contri-
+butions are monitored by the NSPR group (mailto:freier).
+
+All API items exported by these functions will contain the same three
+character prefix, "PL_" (Portable Library). Internal function names
+that are not exported (static) are of little concern, though some caution
+must be used on those elements that are 'extern' but not really intended
+to be part of the API. Those should all have a prefix of "_PL_" (is that
+legal?).
+
+The responsibility for contributions in this area are distributed among
+all interested parties.

+** Name: thrashgc
+**
+** Description: test garbace collection functions.
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
