Edit Question
Title
Body
I'm working on the so called Hotspot open source project, and looking at the implementation I found a nasty nested union in struct looking like that: typedef struct RC_model_t_st { union { struct block_model_t_st *block; struct grid_model_t_st *grid; }; /* block model or grid model */ int type; thermal_config_t *config; }RC_model_t; As far as I'm aware in C/C++ that union is unaccesible. So how someone can make use of union declared in such manner and for what purpose? Thanks!
