I have a file on windows. I’m writing in C++. I have a problem where I need to remove some bytes from the end of the file. I am using ifstream, but I don’t know how to remove those chars, simple put ‘\0’ in the file or what ?

On linux machines, use truncate():

On the Windows machines, use SetEndOfFile():

Both are OS dependent calls.
