#includeThis example demonstrates how to use `raw_ostream` to write to a file. The `llvm::raw_ostream` constructor takes a file name and a boolean indicating whether to append to an existing file or overwrite it. The `<<` operator is used to write the string to the stream, and the `flush()` method is called to ensure that the output is actually written to the file. Overall, the `raw_ostream` class provides a simple and efficient way to output data to streams. Its low-level nature makes it well-suited for situations where fine control over output is needed, such as when writing to a file or communicating with a device.int main() { llvm::raw_ostream ofs("output.txt", true); ofs << "This is some output\n"; ofs.flush(); return 0; }
