/**
* gtk_source_language_manager_guess_language:
* @lm: a #GtkSourceLanguageManager.
* @filename: a filename in Glib filename encoding, or %NULL.
* @content_type: a content type (as in GIO API), or %NULL.
*
* Picks a #GtkSourceLanguage for given file name and content type,
* according to the information in lang files. Either @filename or
* @content_type may be %NULL. This function can be used as follows:
*
* <informalexample><programlisting>
* GtkSourceLanguage *lang;
* lang = gtk_source_language_manager_guess_language (filename, NULL);
* gtk_source_buffer_set_language (buffer, lang);
* </programlisting></informalexample>
*
* or
*
* <informalexample><programlisting>
* GtkSourceLanguage *lang = NULL;
* gboolean result_uncertain;
* gchar *content_type;
*
* content_type = g_content_type_guess (filename, NULL, 0, &result_uncertain);
* if (result_uncertain)
* {
* g_free (content_type);
* content_type = NULL;
* }
*
* lang = gtk_source_language_manager_guess_language (manager, filename, content_type);
* gtk_source_buffer_set_language (buffer, lang);
*
* g_free (content_type);
* </programlisting></informalexample>
*
* etc. Use gtk_source_language_get_mime_types() and gtk_source_language_get_globs()
* if you need full control over file -> language mapping.
*
* Returns: a #GtkSourceLanguage, or %NULL if there is no suitable language
* for given @filename and/or @content_type. Return value is owned by @lm
* and should not be freed.
*
* Since: 2.4
