bool utility::file::create_blank_file ( std::string const & blank_file )

Create a blank file if it doesn't already exist.

bool utility::file::create_directory ( std::string const & dir_path )

Create a directory if it doesn't already exist.

Code is based on a discussion on this web site:

http://www.brainbell.com/tutorials/C++/Creating_A_Directory.htm

On non-Windows systems, the permissions are solely determined by the umask. If directory creation is successful, the function returns true.

*** Currently untested on Windows! If you find it works, remove this warning. Thanks. ***

bool utility::file::create_directory_recursive ( std::string const & dir_path )

Create a directory and its parent directories if they doesn't already exist.

Based on the above create_directory() function. If directory creation is successful or the directory already exists, the function returns true.
