gio:content-type-mime-dirs ()

dirs -- a list of directories to load MIME data from, including any file/ subdirectory, and with the first directory to try listed first

The g:content-type-mime-type function gets the list of directories which MIME data is loaded from. This function is intended to be used when writing tests that depend on information stored in the MIME database, in order to control the data.

Since 2.60 The corresponding g_content_type_set_mime_dirs() setter function is not implemented in the Lisp library.
