stdio_ostream represents an async ostream derived from a standard synchronous stream, as defined by the "std" namespace. It is constructed from a reference to a standard stream, which must be valid for the lifetime of the asynchronous stream.

Detailed Description
template<typename CharType>
class Concurrency::streams::stdio_ostream< CharType >
stdio_ostream represents an async ostream derived from a standard synchronous stream, as defined by the "std" namespace. It is constructed from a reference to a standard stream, which must be valid for the lifetime of the asynchronous stream.
- Template Parameters
-
CharType The data type of the basic element of the
stdio_ostream .
Since std streams are not reference-counted, great care must be taken by an application to make sure that the std stream does not get destroyed until all uses of the asynchronous stream are done and have been serviced.
