Description
An rwGuard manipulator creates a temporary guarded stream that locks the internal mutex of the preceding synchronized stream. In this way, any insertions or extractions following the manipulator within the statement will be atomic, that is, uninterrupted by any other threads. Note that if the preceding stream is not a synchronized stream, the rwGuard manipulator has no effect.
Example
// Lock the stream for the duration of all three insertions: ostr << rwGuard << data1 << data2 << data3;
