Note that I'd not like to use WinAPI calls. Is there any option to improve one of solution mentioned above or is there any other way to achieve my goal? This solution has the best potential but I can't make it override file content in any way - every method that writes file content appends instead of writing to beggining. First, download and install My Lockbox by going to the My Lockbox page on the FSPro Labs website and clicking the Download button. Third and last idea I came with is to open file in ab+ mode: fopen_s(&fp, file_path, "ab+") įread(buffer, sizeof(char), file_size, fp) įwrite("hello", 1, 5) // does not work - appends to end of file

Here, I could not find information whether freopen_s preserves file lock but I suppose that it does not. That's the second idea: fopen_s(&fp, file_path, "rb") This is the idea I came with: fopen_s(&fp, file_path, "rb") īut this solution generates small time window when file is not locked by process. By doing so, the file is unlocked, and you can delete it.I'd like to open file, read it's content and then fully override it.Īpart from that I'd like this file to be locked by process during whole procedure.
