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 <experimental/filesystem>
#include <fstream>
#include <iostream>
#include <string>
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"
