This function will set a list of properties on an existing object instance.

The variadic parameters are a list of pairs of (propname, propvalue) strings. The propname of %NULL indicates the end of the property list.

Update an object's properties Error *err = NULL; Object *obj = ...get / create object...;

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

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