g_object_new shared memory
Hi, I'm using GLib in my application, and I'm using g_object_new to allocate memory of an object. As in C++ specification, there is "new" placement technique that can allow us to place a new object into our predefined memory region. And we can also do with malloc by redefine the malloc fuction. I wonder if we can do it with g_object_new or not? The purpose is to have g_object_new to allocate memory on my own memory region.

I don't think it's possible because g_type_create_instance() has the allocation function hardcoded (g_slice_alloc0() at this moment).

Can I change the g_slide_alloc0 to use my own alloc function so that it can be allocated in a shared region? Or can I override the constructor of my class so that the private data is allocated in a shared region, then in other application, I'll reconstruct the object using g_object_new and then set the private data pointer manually?
