You can get the special path of windows in modern C++.
- C++17
You can get the desktop path in the following cases.
If it fails, a runtime_error is thrown.
#include <filesystem>
#include <ShlObj.h>
#include "pathwrap.hpp"
std::filesystem::path path = pathwrap::get_special_path(CSIDL_DESKTOP);
If you don't want to be thrown an exception:
#include <filesystem>
#include <optional>
#include <system_error>
#include <ShlObj.h>
#include "pathwrap.hpp"
std::error_code code;
std::filesystem::path path_code = pathwrap::get_special_path(CSIDL_DESKTOP, code);
std::filesystem::path path_code = pathwrap::error_code::get_special_path(CSIDL_DESKTOP, code);
// this uses error_code instead of throwing an exception.
// The error_code namespace is an inline namespace, so both are the same.
std::optional<std::filesystem::path> path_optional = pathwrap::optional::get_special_path(CSIDL_APPDATA);
// You can also use std::optional.
if (!path_code) {
// Processing when acquisition of special path is successful.
}
if (path_optional.has_value()) {
// Processing when acquisition of special path is successful.
}
Of course, you can also get many paths other than desktop.
pathwrap::get_special_path(CSIDL_MYVIDEO);
pathwrap::get_special_path(CSIDL_WINDOWS);
pathwrap::get_special_path(CSIDL_STARTUP);
pathwrap::get_special_path(CSIDL_MYDOCUMENTS);
pathwrap::get_special_path(CSIDL_FAVORITES);
