1. 5 emfield.module \emfield_system_list()
2. 6.3 deprecated/emfield-deprecated.inc \emfield_system_list()
3. 6.2 emfield.module \emfield_system_list()

Return an array of installed .inc files and/or loads them upon request. This routine is modeled after drupal_system_listing() (and also depends on it). It's major difference, however, is that it loads .inc files by default.

Parameters

$provider: Optional; name of the passed $provider to find (e.g. "youtube", "google", etc.).

$load: Defaults to TRUE; whether to include matching files into memory.

Return value

An array of file objects optionally matching $provider.
