NAME

std::experimental::filesystem::recursive_directory_iterator::disable_recursion_pending - std::experimental::filesystem::recursive_directory_iterator::disable_recursion_pending

Synopsis

void disable_recursion_pending(); (filesystem TS)

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 increment is called, the iterator will advance within the current directly
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 recursion_pending(),
which is false after this call. It is reset back to true after increment, 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 <fstream>
#include <iostream>
#include <string>
#include <experimental/filesystem>
namespace fs = std::experimental::filesystem;

int main()
{
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");
for(auto i = fs::recursive_directory_iterator("sandbox");
i != fs::recursive_directory_iterator();
++i ) {
std::cout << std::string(i.depth(), ' ') << *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");
}

Output:

"sandbox/a"
"sandbox/a/b"
"sandbox/syma" -> "a"
