Title
Body
I'm trying to open a binary file for writing without erasing the content. But I do not want to write to eof. I want to write to a specific position in file. Here is a litte example: ofstream out("test.txt", ios::binary | ios::app); for(int i = 0; i < 100; i++) out.put('_'); out.write("Hallo", 5); out.close(); ofstream out2("test.txt", ios::binary | ios::app); out2.seekp(10); out2.write("Welt", 4); out2.close(); If using app, seek doesn't work. If not using app opening file erases data. Does anybody know an answer?
