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

Description

get_threading_attribGetThreadingAttrib determines the type of threading object passed to ThreadingHandlethreadingHandlethreading_handle and the attributes the threading object was created with.

Execution information

Execution information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).

• Multithreading scope: global (may be called from any thread).

• Processed without parallelization.

Parameters

ThreadingHandlethreadingHandlethreading_handle (input_control) number → (integer)HTuple (Hlong)HTuple (int / long)intHtuple (Hlong)

Threading object.

ThreadingClassthreadingClassthreading_class (output_control) string-array → (string)HTuple (HString)HTuple (string)Sequence[str]Htuple (char*)

Class name of threading object.

AttribNameattribNameattrib_name (output_control) string-array → (string)HTuple (HString)HTuple (string)Sequence[str]Htuple (char*)

Name of an attribute.

AttribValueattribValueattrib_value (output_control) number-array → (string / integer / real)HTuple (HString / Hlong / double)HTuple (string / int / long / double)Sequence[Union[int, float, str]]Htuple (char* / Hlong / double)

Value of the attribute.

Result

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