[OMPI devel] use of OBJ_NEW and related calls

2016-10-10 Thread Emani, Murali
Hi, Could someone help me in understanding where the functions OBJ_NEW/ OBJ_CONSTRUCT/ OBJ_DESTRUCT are defined in the source code. Are these specific to OpenMPI code base? Is the assumption correct that these calls are wrappers to create new objects, initialize and destroy, similar to any obje

These macros are defined in opal/class/opal_object.h. We are using them all over the OMPI code base, including OPAL, ORTE, OSHMEM and OMPI. These calls are indeed somewhat similar to an OO language, the intent was to have a thread-safe way to refcount objects to keep them around for as long as they

Murali, please note that OBJ_NEW is the macro that allocates (e.g. malloc) and initializes an object among other things, initialization sets the refcount to 1. the OBJ_RETAIN and OBJ_RELEASE macro can then be used in order to increment and decrement the refcount. when the refcount drops t
