Original description The description as published by the source.
A ThreadX module reaches a kernel object's delete service through the Module Manager's dispatch layer, which asked one question about the pointer: does the object lie outside the module's own code and data. That is the policy for using an object, and using an object a module does not own is supported and intended — txm_module_object_pointer_get_extended searches the system's created objects by name and hands back objects the application created and objects other modules created, so that a module can send to a shared queue, take a shared semaphore or get a shared mutex.
Destroying one of those is not sharing it. A module could name any object it had a pointer to and have the privileged dispatcher delete it.
