std::filesystem::recursive_directory_iterator::increment

STD：：文件系统：：递归[医]目录[医]迭代器：：Operator++，std：：file system：：递归[医]目录[医]迭代器：：增量

recursive_directory_iterator& operator++(​(since C++17)
recursive_directory_iterator& increment( std::error_code& ec ​(since C++17)

将迭代器推进到下一个条目。

如果当前迭代目录中没有更多的条目，则在父目录上继续迭代。如果父目录中没有可以迭代的同级条目，则会重复此过程。如果已递归迭代的目录层次结构的父级达到%28，则在depth() == 0)，，，*this设置为结束迭代器。

否则，如果*this引用一个目录，如果满足以下条件，则将其迭代到目录中：

  • disable_recursion_pending()未在此增量之前调用，即recursion_pending() == true...

  • 目录不是符号链接，或者启用以下符号链接，即

!is_symlink(this->symlink_status()) ||

%28选项%28%29及目录[医]选项：：遵循[医]目录[医]符号链接%29%21=0%29。

参数

ec-error code to store the error status to

返回值

*this...

例外

1%29std::filesystem::filesystem_error如果发生错误。错误代码被设置为导致故障的错误的适当错误代码。
