I am trying to find out how to deal with string variables. Do I have to allocate the memory before calling mca_base_component_var_register() or not? It seems it does a strdup() meaning it has to be free()'d while closing the component. Looking at other occurrences of string variables I see different usages. Sometimes it set to NULL sometimes not. Before following a wrong example maybe someone can tell me what the correct usage is.
