As you have been tagged with C++, it may be beneficial to utilizestd::copyinstead ofmemcpybecause the former has a weaker constraint. This is because, in your situation, only the destination iterator needs to be outside the copying range, which is fulfilled. How to copy arrray to array ...
C copy array memcpy Code Example, C answers related to “c copy array memcpy” c malloc array; How to change an array in a function in c; n no of array in c using malloc; how to dynamically allocate array size in c; array value from user c; copy array of integers in c; How to...
note you should prefer std::copy over memcpy. Especially when dealing with STL containers: 12345 // basically it works like this: std::copy( src, src + size, dest ); // so, you would do this: std::copy( pnIntArray, pnIntArray + 1, vIntVector.begin() );Jan...

This is a correctness issue: When -fno-builtin is used, we must assume that we could be compiling the memcpy/memset implementations, so generating calls to them is problematic. Benchmark 1 (3 runs): ./release/bin/zig build -Doptimize=ReleaseFast -Dno-lib -Denable-llvm=false -Duse-llvm...

What I need to know then is how to get string text as a std::wstring from a Windows control or window!May be you can try something likeCString str; ::GetWindowText(m_hWnd,(LPTSTR) (LPCTSTR)str,100); std::wstring wstr = str;Thanks...
