voiddisable_recursion_pending();(since C++17)Disables recursion to the currently referred subdirectory, if any.
The call modifies the pending recursion flag on the iterator in such a way that the next time
is called, the iterator will advance within the current directory even if it is currently referring to a subdirectory that hasn't been visited.
The status of the pending recursion flag can be queried with
, which is false after this call. It is reset back to true after
, and its initial value is also true.
The behavior is undefined if *this is the end iterator.
Parameters
(none)
Return value
(none)
Exceptions
May throw implementation-defined exceptions.
Example
Run this code
#include<cstdlib>#include<filesystem>#include<fstream>#include<iostream>#include<string>namespacefs=std::filesystem;intmain(){fs::current_path(fs::temp_directory_path());fs::create_directories("sandbox/a/b/c");fs::create_directories("sandbox/a/b/d/e");std::ofstream("sandbox/a/b/file1.txt");fs::create_symlink("a","sandbox/syma");std::system("tree sandbox");for(autoi=fs::recursive_directory_iterator("sandbox");i!=fs::recursive_directory_iterator();++i){std::cout<<std::string(i.depth()*2,' ')<<*i;if(fs::is_symlink(i->symlink_status()))std::cout<<" -> "<<fs::read_symlink(*i);std::cout<<'\n';// do not descend into "b"if(i->path().filename()=="b")i.disable_recursion_pending();}fs::remove_all("sandbox");}Possible output:
sandbox ├── a │ └── b │ ├── c │ ├── d │ │ └── e │ └── file1.txt └── syma -> a "sandbox/a" "sandbox/a/b" "sandbox/syma" -> "a" See also
