Is there a way to get field associated with content type? I have to do some functionality with fields associated with a content type, this i have to do before creating content for it.

In custom module tried using node_type_load('digital_iq_2012'), this function loads content type details alone and not the fields associated. 

Do we have a way to get the fields as well?

Any help?
You can use field_info_instances('node', $content_type).

With field_info_instances('node', 'article'), I get the following.
