Yes. Something like that.

Suppose you compiled your library as "myawesomelib.dll" and your
package.cpath is "?.dll" and your open function is
"luaopen_myawesomelib", then:

package.cpath = '?.dll'
require 'myawesomelib'


If your luaopen_myawesomelib() "returns" a table (i.e.: it leaves a
table at the top of the stack), then you can assign it to a local:

local mylib = require 'myawesomelib'

Also, package.loaded[ "myawesomelib" ] will contain the same table
aforementioned. In fact, it will hold anything your loader function
returns. You could return a string, a number, a function etc. If you
return "nil" or don't return anything at all, then it will be set to
"true" (boolean).
