Inotify-cpp is a C++ wrapper for the linux inotify tool. It lets you watch for filesystem events on your filesystem tree.
#include <inotify/Inotify.h>
#include <inotify/FileSystemEvent.h>
#include <boost/filesystem.hpp>
int main(int argc, char** argv){
if(argc <= 1){
std::cout << "Usage: ./a.out /path/to/path/dir" << std::endl;
exit(0);
}
// Directory to watch
boost::filesystem::path dir(argv[1]);
// Init inotify
std::cout << "Setup watches for " << dir <<"..." << std::endl;
Inotify inotify(IN_CREATE | IN_MODIFY | IN_DELETE | IN_MOVE);
// Watch a directory (plus all subdirectories and files)
inotify.watchDirectoryRecursively(dir);
inotify.ignoreFileOnce("file");
// Wait for event of this directory
std::cout << "Waiting for events..." << std::endl;
while(true){
FileSystemEvent event = inotify.getNextEvent();
std::cout << "Event wd(" << event.wd << ") " << event.getMaskString() << "for " << event.path << " was triggered!" << std::endl;
}
return 0;
}
