How programatically cause uploads folder to be created?

Question

My plugin uses the uploads folder to store some files for configuration (as that folder is writable on all installs and I've had issues with Wordpress deleting files elsewhere on some installations).

However, when WordPress is first created, there's no uploads folder. If you manually go to the media section and upload something, it will create it, but I want to be able to do this programmatically. Is there a way?

This should work - using wp_upload_dir to get the path, then checking to see if it exists - and creating it if it doesn't.

$upload_dir = wp_upload_dir();
if (!is_dir($upload_dir['path'])) {  // directory doesn't exist
    mkdir($structure, 0744, true); // the mode to use here may vary based on your hosting environment
}
