◆ resolve_attachment()

void resolve_attachment	(	struct Menu *	menu,
		const struct ConfigSubset *	sub,
		int	index,

static

Advance the Attachment List selection after an action.

Parameters

menu	Menu
sub	Config subset
index	Original menu index, before the action
num	Number of selected attachment entries operated on

If $resolve is set, move the selection on by the number of items that were acted upon. Overruns are silently capped at the end of the list.

Nothing is moved when operating on a tag-prefix selection.
