Why would I use

Hi Geir:
Not sure if the later is "hymem_allocate_memory(int size)"? If so,
they are the same indeed, and the later is the a macro. Everytime
before we use the macro, call "PORT_ACCESS_FROM_ENV (env)"
e.g.:
somemethod(JNIEnv * env, ...){
PORT_ACCESS_FROM_ENV (env);
...
hymem_allocate_memory(sizeof(something));
...
}
And they are defined in hyport.h. :)
Yes, they are same in general case. And I think the hymem_xxxx_xxx
usage is prefered, because they are more handy and they encapsulate the
HyPortLibrary's structure.
However, sometimes the two usage maybe different, it is possible to
create multiple HyPortLibrary instance within one VM instance, and the
developer can specify which HyPortLibrary instance he wants to use by
explicitly invoke portLib->blabla.
