C++ : lifetime of stream requests?

[Christian Rivasseau]

Hi,

in ClientAsyncReaderWriter::Write(const T& msg, tag),

is it OK do delete 'msg' after Write() returns, or should it be

kept alive until 'tag' was notified?

Thanks a lot,

Excellent question! From a C++ API perspective, we only guarantee that any part of the Write (including serialization) is done when the tag is posted, so the only safe option is to keep the data valid until the tag is posted. This may become an issue, for example, for serialization alternatives or optimizations.
