IDebugEngineLaunch2::LaunchSuspended

  • Article

This method launches a process by means of the debug engine (DE).

Syntax

int LaunchSuspended(
   string               pszServer,
   IDebugPort2          pPort,
   string               pszExe,
   string               pszArgs,
   string               pszDir,
   string               bstrEnv,
   string               pszOptions,
   enum_LAUNCH_FLAGS    dwLaunchFlags,
   uint                 hStdInput,
   uint                 hStdOutput,
   uint                 hStdError,
   IDebugEventCallback2 pCallback,
   out IDebugProcess2   ppProcess
);

Parameters

pszMachine
[in] The name of the machine in which to launch the process. Use a null value to specify the local machine.

pPort
[in] The IDebugPort2 interface representing the port that the program will run in.

pszExe
[in] The name of the executable to be launched.

pszArgs
[in] The arguments to pass to the executable. May be a null value if there are no arguments.

pszDir
[in] The name of the working directory used by the executable. May be a null value if no working directory is required.

bstrEnv
[in] Environment block of NULL-terminated strings, followed by an additional NULL terminator.

pszOptions
[in] The options for the executable.

dwLaunchFlags
[in] Specifies the LAUNCH_FLAGS for a session.

hStdInput
[in] Handle to an alternate input stream. May be 0 if redirection is not required.

hStdOutput
[in] Handle to an alternate output stream. May be 0 if redirection is not required.

hStdError
[in] Handle to an alternate error output stream. May be 0 if redirection is not required.

pCallback
[in] The IDebugEventCallback2 object that receives debugger events.

ppDebugProcess
[out] Returns the resulting IDebugProcess2 object that represents the launched process.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

Normally, Visual Studio launches a program using the LaunchSuspended method and then attaches the debugger to the suspended program. However, there are circumstances in which the debug engine may need to launch a program (for example, if the debug engine is part of an interpreter and the program being debugged is an interpreted language), in which case Visual Studio uses the IDebugEngineLaunch2::LaunchSuspended method.

The ResumeProcess method is called to start the process after the process has been successfully launched in a suspended state.
