Hello All,
We are opening a network file on Windows using the CreateFile API. According to MSDN, the flags FILE_FLAG_NO_BUFFERING and FILE_FLAG_WRITE_THROUGH should bypass local caching and write directly to disk. However, we observe that the file still opens with an opportunistic lock. Could you advise if there are additional attributes or flags that can be used to prevent this?
Thank you very much
CreateFile(“FileName”,GENERIC_WRITE, FILE_SHARE_WRITE,
NULL,(COPY_FILE_FAIL_IF_EXISTS & dwCopyFlags) ? CREATE_NEW : CREATE_ALWAYS,
FILE_FLAG_NO_BUFFERING | FILE_FLAG_WRITE_THROUGH , NULL);
