guess_language

Picks a SourceLanguage 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:

	GtkSourceLanguage *lang;
	lang = gtk_source_language_manager_guess_language (filename, NULL);
	gtk_source_buffer_set_language (buffer, lang);

or

	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);

etc. Use get_mime_types and get_globs if you need full control over file -> language mapping.

Parameters:

this	a SourceLanguageManager.
filename	a filename in Glib filename encoding, or null.
content_type	a content type (as in GIO API), or null.

Returns:

a SourceLanguage, or null if there is no suitable language for given filename and/or content_type. Return value is owned by this and should not be freed.
