When I added rename operations, at the time it seemed like a good idea to make the last argument (which would otherwise have been const char *oldpath) optional.

添加重命名操作在那时就像是添加最后一个可选参数（否则可能应为 const char *oldpath）一样，算是很好的主意。

These versions of exec* are just various calling interfaces for core function execve(): int execve(const char *filename, char *const argv [], char *const envp[]).

exec*的这些版本只是内核函数execve() （int execve(const char *filename, char *constargv [], char *constenvp[])） 的各种调用接口。

path operator / (char* lhs, const path& rhs): This routine is a non-member function of path.

pathoperator / (char*lhs,const path&rhs)：此例程是 path 的非成员函数。
