After GetLastError() I get 5 - "ERROR_ACCESS_DENIED 5 (0x5) Access is denied". The file has createfilemapping example been created after CreateFile with no problem, but following CreateFileMapping never has bee succesful. int MapDestFile(LPCWSTR fPath) { hDestFile = CreateFile( fPath, GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); if (hSourceFile == NULL) { printf("%d\n", GetLastError()); } hDestMapFile = CreateFileMapping( hDestFile, NULL, PAGE_READWRITE, 0, 10, NULL ); if (hDestMapFile == NULL) { // here always tell error number 5 printf("%d\n", GetLastError()); } lpMapAddressDestFile = MapViewOfFile( hDestMapFile, FILE_MAP_WRITE, 0, 0, 0); if (lpMapAddressDestFile == NULL) { printf("%d\n", GetLastError()); } return 1; } I would appreciate any suggestions.

to do*anything* with cygwin:d:\cygwin\bin\bash.exe: *** CreateFileMapping, Win32 error 5. Terminating.What's odd is this doesn't happen immediately, it happens after a cron taskthat uses rsync to make backups to an rsync server has run. I think itprobably has more to do with the cron daemon than rsync but god knows whatthe problem is.I've checked other messages on this subject and they seem to refer to filepermissions etc. but my entire cygwin directory tree is accessible to anyvalid user on my machine and ls -l shows all permissions as rwx.Does someone have any clues as disabling my auto backups isn't a goodsolution? :-)---------------------------------Q-Games, Dylan Cuthbert.http://www.q-games.com Larry Hall 2003-10-09 17:02:01 UTC PermalinkRaw Message Post by Dylan CuthbertHi there,I updated Cygwin yesterday and now I get this error whenever I try to dod:\cygwin\bin\bash.exe: *** CreateFileMapping, Win32 error 5.
