+--------------------
+03o,24apr16,yjl  Fix VXW6-85230, dosFsVolFormat() in usrAppInit() sometimes
+                 fails.
+03n,29apr10,pad  Moved extern C statement after include statements.
+03m,21nov08,hps  fix defect WIND00141563: Rawfs does not check validity
+                 of file descriptor pointers
+03l,25aug05,jlk  Added S_rawFsLib_WRITE_ONLY errno.
+03k,09feb05,rfr  Modified to use the XBD interface.
+03j,30apr02,jkf  SPR#75255, corrected unneeded API change.
+03i,20sep01,jkf  SPR#69031, common code for both AE & 5.x.
+03h,29feb00,jkf  T3 cleanup
+03g,30dec99,jkf  rawFsDevInit() changed from void* to CBIO_DEV_ID
+03f,31jul99,jkf  changes for CBIO API.
+03e,31jul99,jkf  T2 merge, tidiness & spelling.
+03d,15oct98,lrn  moved 64-bit extended ioctl codes to ioLib.h
+03c,08oct98,vld  added definition of RAWFS_DEF_MAX_FILES
+03b,08oct98,vld  driver interface changed to CBIO_DEV.
+		 replaced rawvd_pBlkDev with CBIO_DEV * rawVdCbio
+    	    	 changed prototype of rawFsDevInit().
+03a,23jul98,vld  added ioctl codes for 64-bit ioctl requests; new error codes.
+02b,22sep92,rrr  added support for c++
+02a,04jul92,jcf  cleaned up.
+01d,26may92,rrr  the tree shuffle
+01c,04oct91,rrr  passed through the ansification filter
+		  -changed VOID to void
+		  -changed copyright notice
+01b,05oct90,shl  added ANSI function prototypes.
+                 added copyright notice.
