$Log: MoreOSL.c,v $
Revision 1.10 2003/05/20 15:49:53
<rdar://problem/3263387> Initialise "err" in ClassAccessorByName.
Revision 1.9 2002/11/08 23:48:02
Include our prototype early to flush out any missing dependencies. Adopt MoreAEDataModel. Convert nil to NULL. Convert MoreAssertQ to assert.
Revision 1.8 2001/11/07 15:54:00
Tidy up headers, add CVS logs, update copyright.
<7> 21/9/01 Quinn Changes for CWPro7 Mach-O build.
<6> 15/2/01 Quinn Minor tweaks to get it building under Project Builder.
<5> 25/4/00 Quinn Don't set result in reply if event is defined not to return a
result and the result is null.
<4> 27/3/00 Quinn Fix debug build. Support pClass. Avoid assert in MOSLCountProc.
Futz with error codes in formRange. Fix derived types in
PseudoCListCount. Support get data on raw data in DispatchEvent.
Support typeAlias like pseudo-cFile.
<3> 20/3/00 Quinn Replaced debug Boolean with individual flags. Implemented
formRange. Exposed routines for "make" event handlers to
support "with properties". General access by name and ID.
"coerceToken" object primitive. Many minor changes.
<2> 9/3/00 Quinn Changes to support strings beyond Str255.
<1> 6/3/00 Quinn First checked in.
