Unigine::Dir Class

Header: #include <UnigineDir.h>

This class allows the user to retrieve various directory attributes, including file specific information. Also, the class provides the ability to copy files to different directories.

Usage Example

Here is an example of how to print out names of all nested directories in the specified directory:

Source code (C++)
// create a descriptor for the specified directory and open it
Unigine::DirPtr dir = Unigine::Dir::create();
dir->open("path"); //write your path string

// loop through all nested directories and print their names
int num_dirs = dir->getNumDirs();
for (int i = 0; i < num_dirs; ++i)
{
const char* dirname = dir->getDirName(i);
Unigine::Log::message("Dir name %s\n", dirname);
}

// close the directory descriptor
dir->close();
