wonx/comm.c
Hiroaki Sakai 103ffe29f1 We implemented mmap (). Specifically, see README.
Added service function.  (A service function dumping information for debugging,
Added service function for screen drawing ON / OFF control) Specifically, see README.

Make the object's destructor called from bios_exit ()
Add appropriate Destroy function to each object.  Delete objects properly
We have checked the termination process as a whole, as done.

Fix to accept interrupts even during key_wait ().
(Previously, only key input was accepted)

Some timer interrupts are improved.  (UNIXTimer.c)

Change the wonx_include directory to wonx.

Changed to search the full path to perl automatically and insert it at the beginning of perl script.

Makefile review, improvement.

Changed ON / OFF of screen drawing to switch according to display level.
(See README for details.)
Also change to display level lowered by F9 and display level raised by F10.
In accordance with that, we have reviewed a part of ON / OFF part of drawing and key input event processing.

Fixed to display message when pressing key.

Obj ObjListData_GetPrev (ObjListData data)
Obj ObjListData_GetNext (ObjListData data)
To
ObjListData ObjListData_GetPrev (ObjListData data)
ObjListData ObjListData_GetNext (ObjListData data)
Fixed to.

Added install, uninstall target to Makefile.  Fixed challsrc.sh.
