C# to QT4.8.7 code conversion

I have a small code of approx 300 code lines, to be converted from C# to QT4.8.7 c++ i am pasting a small C# code snippet, to give you a idea., private static int printf_close(List<byte[]> e, int pos) { int length = 0; for (int n = pos + 1; n < [login to view URL]; n++) { length += e[n].Length; } byte[] baLength = [login to view URL](length); e[pos][2] = baLength[3]; e[pos][3] = baLength[2]; e[pos][4] = baLength[1]; e[pos][5] = baLength[0]; return 0; }
