+/**
+ * Retrieve information about a CRTC:s gamma ramps, 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   crtc   The name of the CRTC
+ * @param   info   Output parameter for the information, must be initialised
+ * @param   ctx    The state of the library, must be connected
+ * @return         Zero on success, -1 on error, in which case `ctx->error`
+ *                 (rather than `errno`) is read for information about the error
