I/o Error 32 Game Maker
down vote favorite 1 I have a Delphi 2006 app that writes to a file and then regularly renames it to a sequenced name, and creates a new one, i.e. open file.dat write a record to file.dat close file.dat ... open file.dat write a record to file.dat close file.dat rename file.dat to file20110818123456.dat create file.dat open file.dat write a record to file.dat close file.dat ... The problem is that occasionally the einouterror rename fails with Error 32 - The process cannot access the file because it is being used by another process. I am checking that the destination of the rename doesn't exist. It's as if the close of the file after writing a record doesn't happen immediately. I added a loop in the rename procedure to sleep for a bit and try again up to 10 times but that doesn't help. function RenameFileAtAllCosts (const OldFileID : TFilename ; const NewFileID : TFilename ; out ErrorCode : Integer) : boolean ; const MaxRenameAttempts = 10 ; var RenameAttempts : integer ; begin Result := FileExists (OldFileID) ; if (Result = true) then begin if FileExists (NewFileID) then begin Result := DeleteFile (PChar (NewFileID)) ; end ; if (Result = true) then begin Result := (not FileExists (NewFileID)) ; end ; if (Result = true) then begin RenameAttempts := 0 ; repeat SysUtils.Sleep (50) ; Result := RenameFile (OldFileID, NewFileID) ; inc (RenameAttempts) until (Result or (RenameAttempts >= MaxRenameAttempts)) ; end ; end ; if (not Result) then begin ErrorCode := GetLastError ; end ; end ; * ADDITIONAL INFO * This is the ProcMon log of the relevant disk I/O, with the associated Pascal source or psuedo-code preceding each block open file.dat w

Thanks Ralph. Your pointers helped us fix the problem. For the record, here's the story: After digging around the Windows.pas files and all other .pas files http://www.delphigroups.info/2/a7/334575.html containing the word "sharing" I discovered that error code 32 is a generic code for any "undefined" I/O error. ( To quote commdlg.pas: "Note: Undefined return values map to OFN_SHAREWARN, but are reserved for future use.") By stepping and guessing we traced it to a line in a previous function "RmDir(MyDirName)" that failed. Since we were not trapping IO errors with IOResult then all subsequent IO failed (as per help file - - "If an I/O error occurs and I/O-checking is off, all subsequent I/O operations are ignored until a call is made to IOResult. Calling IOResult clears the internal error flag".) Only RmDir causes this and not RemoveDir. So we are now using RemoveDir. Most of the time (all the time?) RemoveDir (and RmDir) fail. Not serious but peculiar.
