std::filesystem::directory_entry::is_regular_file

Since C++17

Checks whether the pointed-to object is a regular file. Effectively returns:

# Declarations

bool is_regular_file() const;

(since C++17)

bool is_regular_file( std::error_code& ec ) const noexcept;

(since C++17)

# Parameters

# Return value

true if the referred-to filesystem object is a regular file, false otherwise.

# Example

#include <filesystem>
#include <iostream>
#include <string>
 
namespace fs = std::filesystem;
 
int main(int argc, const char* argv[])
{
    // Print out all regular files in a directory 'dir'.
    try
    {
        const auto dir{argc == 2 ? fs::path{argv[1]} : fs::current_path()};
 
        std::cout << "Current dir: " << dir << '\n'
                  << std::string(40, '-') << '\n';
 
        for (fs::directory_entry const& entry : fs::directory_iterator(dir))
            if (entry.is_regular_file())
                std::cout << entry.path().filename() << '\n';
    }
    catch(const fs::filesystem_error& e)
    {
        std::cout << e.what() << '\n';
    }
}
