CreateProcess()

static MAXON_METHOD Result<SystemProcessObjectRef> CreateProcess ( const Url &  programPath, const ArrayInterface< String > &  arguments, EXECUTEPROGRAMFLAGS  flags, void *  userData, const InOutputStreamRef &  stdinPipe = InOutputStreamRef(), const InOutputStreamRef &  stdoutPipe = InOutputStreamRef(), const InOutputStreamRef &  stderrPipe = InOutputStreamRef()  )

static

Prepares an executable to be executed as a process. If EXECUTEPROGRAMFLAGS::CAPTURELOGFILE is set all pipe parameters will be ignored.

Parameters

[in]	programPath	File path to the executable. It needs to be a valid path to a URLSCHEME_FILESYSTEM path. If an stdout and stderr pipe is used CAPTURELOGFILE will be ignored.
[in]	arguments	Array of parameters to start the executable with.
[in]	flags	See EXECUTEPROGRAMFLAGS flags.
[in]	userData	User data that can be attached to this process.
[in]	stdinPipe	Pipe where stdin is redirected to.
[in]	stdoutPipe	Pipe where stdout is redirected to.
[in]	stderrPipe	Pipe where stderr is redirected to.

Returns

Reference object to a system process.

StartProcessAndWait()

static MAXON_METHOD Result<SystemProcessObjectRef> StartProcessAndWait ( const Url &  programPath, const ArrayInterface< String > &  arguments, EXECUTEPROGRAMFLAGS  flags, ExecuteProgramCallback  callback, void *  userData  )

static

Starts and waits for a process.

Parameters

[in]	programPath	File path to the executable. It needs to be a valid path to a URLSCHEME_FILESYSTEM path.
[in]	arguments	Array of parameters to start the executable with.
[in]	flags	See EXECUTEPROGRAMFLAGS flags.
[in]	callback	Pointer to a Callback function called while the executable is running. See ExecuteProgramCallback.
[in]	userData	User data that can be attached to this process.

Returns

Reference object to a system process. Please note that the process is already done. You can use this handle to determine the log file or the exit code.

GetSystemProcesses()

static MAXON_METHOD Result<void> GetSystemProcesses ( const ValueReceiver< const SystemProcessObjectRef & > &  processes )

static

Enumerates all system processes and returns a list of them.

Parameters

[out]

processes

The receiver for the system processes.

Returns

OK on success.

GetCurrentProcessId()

static MAXON_METHOD UInt GetCurrentProcessId ( )

static

Gets the process ID of the current running process.

Returns

The current process ID.

GetProcess()

static MAXON_METHOD Result<SystemProcessObjectRef> GetProcess ( UInt  id )

static

Creates a process object for the given process ID. The returned object will have only limited capabilities. E.g. you cannot get the logfile or user data.

Parameters

[in]

id

ID of the process you want to create an object for.

Returns

Reference object to a system process.

WaitForProcess()

static MAXON_METHOD Result<WAIT_PROCESS_RESULT> WaitForProcess ( const SystemProcessObjectRef &  processRef, const TimeValue &  timeout  )

static

Waits for the given process to finish.

Parameters

[in]	processRef	Process object to wait for.
[in]	timeout	Timeout to wait for the process to finish.

Returns

Returns whether the process is still running or not.
