* include/hbapierr.h
* src/harbour.def
* src/rtl/errapi.c
+ added new C function:
void hb_errReinit( PHB_ITEM pError );
it allows to replace default error object with user custom one which
support :Init() method
* contrib/xhb/xhb.hbp
+ contrib/xhb/xhb.h
+ contrib/xhb/xhberror.prg
+ added code which extends Harbour error objects adding functionality
known from xHarbour:
oError:ProcName
oError:ProcLine
oError:ProcModule
Above instance variables are initialized automatically when error
object is created.
To enable this functionality it's enough to add to PRG code:
REQUEST xhb_ErrorNew
* contrib/xhb/xhberr.prg
* use error object :Proc*() methods if they are available
- removed PRG version of xhb_ErrorNew()
* contrib/xhb/xhbmemo.prg
* contrib/xhb/xhbtedit.prg
! use xhb_ErrorNew() instead of ErrorNew() which does not support
any parameters
* include/hbapicls.h
