pub unsafe extern "C" fn object_new_with_props(
    typename: *const c_char, 
    parent: *mut Object, 
    id: *const c_char, 
    errp: *mut *mut Error,

) -> *mut Object

object_new_with_props: @typename: The name of the type of the object to instantiate. @parent: the parent object @id: The unique ID of the object @errp: pointer to error object @…: list of property names and values

This function will initialize a new object using heap allocated memory. The returned object has a reference count of 1, and will be freed when the last reference is dropped.

The @id parameter will be used when registering the object as a child of @parent in the composition tree.

The variadic parameters are a list of pairs of (propname, propvalue) strings. The propname of %NULL indicates the end of the property list. If the object implements the user creatable interface, the object will be marked complete once all the properties have been processed.

Error *err = NULL; Object *obj;

obj = object_new_with_props(TYPE_MEMORY_BACKEND_FILE, object_get_objects_root(), “hostmem0”, &err, “share”, “yes”, “mem-path”, “/dev/shm/somefile”, “prealloc”, “yes”, “size”, “1048576”, NULL);

if (!obj) { g_printerr(“Cannot create memory backend: %s\n”, error_get_pretty(err)); }

The returned object will have one stable reference maintained for as long as it is present in the object hierarchy.

Returns: The newly allocated, instantiated & initialized object.
