c–将std::filesystem::path传递给函数段错误 当我尝试使用std :: filesystem :: path作为函数参数时,它会在我的机器上发生段错误.这是一个最小的例子: #include <filesystem> void thing(const std::filesystem::path& p) { return; } int main() { thing("test"); return 0; } 此代码段会导致以...

voidcurrent_path(conststd::filesystem::path&p,std::error_code&ec); (4)(C++17 起) 返回或更改当前路径。 1-2)返回当前工作目录的绝对路径,如同通过 POSIXgetcwd取得(以原生格式)。若错误发生则(2)返回path()。 3-4)更改当前工作目录到p,如同通过 POSIXchdir。

与Combine方法差不多,不过Join方法是把所以参数均按照相对目录来拼接。说完了目录的一些操作,我们看看Path对文件路径提供了哪些支持:public static string GetFileName (string path);获取路径里的文件名,例如说:“C:\mydir\myfile.ext”,返回结果就是“myfile.ext”,也就是说这个方法会返回携带后缀名的文件...
