boost::filesystem 을 이용하여 directory size 알아내기

#include <boost />ilesystem.hpp> #include <iostream> using namespace std; namespace bfs = boost::filesystem; uintmax_t dirSize(const std::string& dirPath, bool recursive = false) { uintmax_t tmpSize = 0; bfs::directory_iterator dirIter = bfs::directory_iterator(dirPath); bfs::directory_iterator dirIterEnd; for(; dirIter != dirIterEnd; dirIter++) { if ( bfs::is_directory(*dirIter) ) { if ( recursive ) tmpSize += dirSize(dirIter->string(), true); continue; } tmpSize += bfs::file_size(*dirIter); } return tmpSize; } int main(int argc, char* argv[]) { if ( argc != 2 ) { cout << "[usage] main dirpath" << endl; return -1; } std::string dirpath(argv[1]); cout "dir(" dirpath ") size : " dirsize(dirpath, true) < />extarea></iostream>
