source: trunk/dll/errutil.c

Last change on this file was 1891, checked in by Steven Levine, 6 years ago

Rework FreeCnrItem to ensure all CNRITEMs deleted.
Use WinSendMsg CMA_NEXT.
Was using preccNextRecord which is not recommended because control does
not maintain linkage after inserts and deletes.
Note: arccnrs.c still needs to be reworked to use common functions from filldir.c.
