+ * List all available CRTC:s, synchronous version
+ * 
+ * This is a synchronous request function, as such,
+ * you have to ensure that communication is blocking
+ * (default), and that there are not asynchronous
+ * requests waiting, it also means that EINTR:s are
+ * silently ignored and there no wait to cancel the
+ * operation without disconnection from the server
+ * 
+ * @param   ctx  The state of the library, must be connected
+ * @return       A `NULL`-terminated list of names. You should only free
+ *               the outer pointer, inner pointers are subpointers of the
+ *               outer pointer and cannot be freed. `NULL` on error, in
+ *               which case `ctx->error` (rather than `errno`) is read
+ *               for information about the error.
