[SDL] SDL_PeepThread() first argument confusion / newbie

[Crono5788]

I'm using SDL_PeepThread() in my program. When I use the ampersand operator to
send it the first argument, i.e. (&events, ...), it works fine. But when I send
it a pointer for an SDL_Event, i.e. (p_events, ...), I get a memory segmentation
fault and the program crashes! Could someone explain why, or at least show me
something else that would explain why? Thanks in advance for the help!
