Construct a yield context to represent the specified coroutine. Construct a yield context from another yield context type. |
|
|
Return a yield context that sets the specified error_code. |
The basic_yield_context
class is used to represent the currently executing stackful coroutine. A
basic_yield_context
may be passed as a handler to an asynchronous operation. For example:
template <typename Handler>
void my_coroutine(basic_yield_context<Handler> yield)
{
...
std::size_t n = my_socket.async_read_some(buffer, yield);
...
}
The initiating function (async_read_some in the above example) suspends the current coroutine. The coroutine is resumed when the asynchronous operation completes, and the result of the operation is returned.
