Be aware that this function/method will block the caller, unless a frame is currently ready to be read. The duration of the block is the currently set read timeout.



The installation default for PECL Stomp read timeout is two seconds. Unless the associated ini file has been modified to override this value, or you have used the "set read timeout" function/method, the block time will be two seconds.
