set_mime_dirs

Set the list of directories used by GIO to load the MIME database.

If dirs is null, the directories used are the default:

• the `mime` subdirectory of the directory in `$XDG_DATA_HOME`
• the `mime` subdirectory of every directory in `$XDG_DATA_DIRS`

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.

Typically, in case your tests use g_test_option_isolate_dirs, but they depend on the system’s MIME database, you should call this function with dirs set to null before calling init, for instance:

  // Load MIME data from the system
  g_content_type_set_mime_dirs (NULL);
  // Isolate the environment
  g_test_init (&argc, &argv, G_TEST_OPTION_ISOLATE_DIRS, NULL);

  …

  return g_test_run ();

Parameters:

dirs	null-terminated list of directories to load MIME data from, including any `mime/` subdirectory, and with the first directory to try listed first
