malcolm: Sun Feb 25 17:23:56 CET 2001 Update of /usr/src/master/nhc/src/prelude/IO In directory hinken:/tmp/cvs-serv18501 Modified Files: HFileSize.hs HFlush.hs HGetPosn.hs HSeek.hs HSetBuffering.hs HSetPosn.hs OpenFile.hs Log Message: These IO functions previously used an Either type through some local extensions to the common FFI, in order to distinguish an error return from a valid one. The extension is deprecated now - so use FFI.getErrNo and friends instead.
