// the specifics of pipes on Windows, some extra steps are required:
|
||
|
//
|
||
|
// 1. The parent creates a communication pipe and stores handles to both
|
||
|
// ends of it.
|
||
|
// 2. The parent starts the child and provides it with the information
|
||
|
// necessary to acquire the handle to the write end of the pipe.
|
||
|
// 3. The child acquires the write end of the pipe and signals the parent
|
||
|
// using a Windows event.
|
||
|
// 4. Now the parent can release the write end of the pipe on its side. If
|
||
|
// this is done before step 3, the object's reference count goes down to
|
||
|
// 0 and it is destroyed, preventing the child from acquiring it. The
|
||
|
// parent now has to release it, or read operations on the read end of
|
||
|
// the pipe will not return when the child terminates.
|
||
|
// 5. The parent reads child's output through the pipe (outcome code and
|
||
|
// any possible error messages) from the pipe, and its stderr and then
|
||
|
// determines whether to fail the test.
|
||
|
//
|
||
|
// Note: to distinguish Win32 API calls from the local method and function
|
||
|
// calls, the former are explicitly resolved in the global namespace.
