+  //! \brief Constructs an instance of InitialClientData. This object does not
+  //!     take ownership of any of the referenced HANDLEs.
+  //!
+  //! \param[in] request_crash_dump An event signalled from the client on crash.
+  //! \param[in] request_non_crash_dump An event signalled from the client when
+  //!     it would like a dump to be taken, but allowed to continue afterwards.
+  //! \param[in] non_crash_dump_completed An event signalled from the handler to
+  //!     tell the client that the non-crash dump has completed, and it can
+  //!     continue execution.
+  //! \param[in] first_pipe_instance The server end and first instance of a pipe
+  //!     that will be used for communication with all other clients after this
+  //!     initial one.
+  //! \param[in] client_process A process handle for the client being
+  //!     registered.
+  //! \param[in] crash_exception_information The address, in the client's
+  //!     address space, of an ExceptionInformation structure, used when
+  //!     handling a crash dump request.
+  //! \param[in] non_crash_exception_information The address, in the client's
+  //!     address space, of an ExceptionInformation structure, used when
+  //!     handling a non-crashing dump request.
+  //! \param[in] debug_critical_section_address The address, in the client
+  //!     process's address space, of a `CRITICAL_SECTION` allocated with a
+  //!     valid .DebugInfo field. This can be accomplished by using
+  //!     InitializeCriticalSectionWithDebugInfoIfPossible() or equivalent. This
+  //!     value can be `0`, however then limited lock data will be available in
+  //!     minidumps.
