示例1: CompleteUnitWaitPushL
/**
* -Reads in the whole Msg. Header & Body From the WSS stack
* (i.e the test Harness) and Creates a Local Copy.
* -Copy the Msg. Header & Body to Watcher Buffers:
* if the Watcher Buffers are big enough to hold the message,
* then the whole Mgs is copied and we Complete with KErrNone.
* if the Watcher Buffers are smaller then the Msg is copied
* in blocks of size equal to the size of the Watcher Buffers
* completing with EMoreData every time until the watcher gets
* the whole Msg. At that point there is no more data to be
* copied then we complete with KErrNone.
