//
// Definition of ProfilingAPIAttachClient, which houses the prime portion of the
// implementation of the AttachProfiler() API, exported by mscoree.dll, and consumed by
// trigger processes in order to force the runtime of a target process to load a
// profiler. This handles opening a client connection to the pipe created by the target
// profilee, and sending requests across that pipe to force the target profilee (which
// acts as the pipe server) to attach a profiler.

// Here's the beef. All the pipe client stuff running in the trigger process (via call to
// AttachProfiler()) is housed in this class. Note that these functions cannot assume a
// fully initialized runtime (e.g., it would be nonsensical for these functions to
// reference ProfilingAPIAttachDetach::s_hAttachEvent). These functions operate solely by
// finding the attach event & pipes by name, and using them to communicate with the
// target profilee app.
