get_threading_attribT_get_threading_attribGetThreadingAttribGetThreadingAttribget_threading_attrib (Operator)

get_threading_attribT_get_threading_attribGetThreadingAttribGetThreadingAttribget_threading_attrib — Query the attributes of a threading / synchronization object.

Signature

get_threading_attrib( : : ThreadingHandle : ThreadingClass, AttribName, AttribValue)

Herror T_get_threading_attrib(const Htuple ThreadingHandle, Htuple* ThreadingClass, Htuple* AttribName, Htuple* AttribValue)

void GetThreadingAttrib(const HTuple& ThreadingHandle, HTuple* ThreadingClass, HTuple* AttribName, HTuple* AttribValue)

static void HOperatorSet.GetThreadingAttrib(HTuple threadingHandle, out HTuple threadingClass, out HTuple attribName, out HTuple attribValue)

def get_threading_attrib(threading_handle: int) -> Tuple[Sequence[str], Sequence[str], Sequence[Union[int, float, str]]]

Description

get_threading_attribget_threading_attribGetThreadingAttribGetThreadingAttribget_threading_attrib determines the type of threading object passed to ThreadingHandleThreadingHandleThreadingHandlethreadingHandlethreading_handle and the attributes the threading object was created with.

Execution Information

• Multithreading type: independent (runs in parallel even with exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

ThreadingHandleThreadingHandleThreadingHandlethreadingHandlethreading_handle (input_control)  number → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Threading object.

Class name of threading object.

AttribNameAttribNameAttribNameattribNameattrib_name (output_control)  string-array → HTupleSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Name of an attribute.

Value of the attribute.

Result

If the threading handle is valid, the operator get_threading_attribget_threading_attribGetThreadingAttribGetThreadingAttribget_threading_attrib returns 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
