如何在boost :: filesystem中使用copy_file？

Question

I want to copy a file from directory to another, but my program always aborts for some reasons.Has anyone done this this before could tell me what was wrong? And how could I catch exceptions was thrown by copy_file , I checked boost site, but I could not find any relevant information about exception.

path user_path( "C:\\My Folder" );
boost::filesystem::create_directory( user_path );
path file(  "C:\\Another\\file.txt" );
boost::filesystem::copy_file( file, user_path );

Thanks,

您必须提供文件名的路径，而不仅仅是它所在的目录。
