+# Warning C6392
+
+> This expression writes the value of the pointer to the stream. If this is intentional, add an explicit cast to 'void *'
+
+This rule was added in Visual Studio 2022 17.8.
+
+## Remarks
+
+C++ supports wide character streams such as `std::wostringstream`, and nonwide character streams such as `std::ostringstream`. Trying to print a wide string to a nonwide stream calls the `void*` overload of `operator<<`. This overload prints the address of the wide string instead of the value.
+
+Code analysis name: `STREAM_OUTPUT_VOID_PTR`
+
+## Example
+
+The following code snippet prints the value of the pointer to the standard output instead of the string `"Pear"`:
+
+```cpp
+#include <iostream>
+
+int main() {
+    std::cout << L"Pear\n"; // Warning: C6392
+}
+```
+
+There are multiple ways to fix this error. If printing the pointer value is unintended, use a nonwide string:
+
+```cpp
+#include <iostream>
+
+int main() {
+    std::cout << "Pear\n"; // No warning.
+}
+```
+
+Alternatively, use a wide stream:
+
+```cpp
+#include <iostream>
+
+int main() {
+    std::wcout << L"Pear\n"; // No warning.
+}
+```
+
+If the behavior is intentional, make the intention explicit and silence the warning by using an explicit cast:
+
+```cpp
+#include <iostream>
+
+int main() {
+    std::cout << static_cast<void*>(L"Pear\n"); // No warning.
+}
+```
