IDebugClient4::CreateProcessAndAttachWide method (dbgeng.h)
The CreateProcessAndAttachWide method creates a process from a specified command line, then attach to another user-mode process. The created process is suspended and only allowed to execute when the attach has completed. This allows rough synchronization when debugging both, client and server processes.
Syntax
HRESULT CreateProcessAndAttachWide(
[in] ULONG64 Server,
[in, optional] PWSTR CommandLine,
[in] ULONG CreateFlags,
[in] ULONG ProcessId,
[in] ULONG AttachFlags
);
Parameters
[in] Server
Specifies the process server to use to attach to the process. If Server is zero, the engine will connect to the local process without using a process server.
[in, optional] CommandLine
Specifies the command line to execute to create the new process. If CommandLine is NULL, then no process is created and these methods attach to an existing process, as AttachProcess does.
[in] CreateFlags
Specifies the flags to use when creating the process. For details on these flags, see DEBUG_CREATE_PROCESS_OPTIONS.CreateFlags.
[in] ProcessId
Specifies the process ID of the target process the debugger will attach to. If ProcessId is zero, the debugger will attach to the process it created from CommandLine.
[in] AttachFlags
Specifies the flags that control how the debugger attaches to the target process. For details on these flags, see DEBUG_ATTACH_XXX.
Return value
This method may also return error values. See Return Values for more details.

The method was successful. |
Remarks
This method is available only for live user-mode debugging.
If CommandLine is not NULL and ProcessId is not zero, then the engine will create the process in a suspended state. The engine will resume this newly created process after it successfully connects to the process specified in ProcessId.
The engine does not completely attach to the process until the WaitForEvent method has been called. Only after the process has generated an event -- for example, the create-process event -- does it become available in the debugger session.
For more information about creating and attaching to live user-mode targets, see Live User-Mode Targets.
