After perusing the web and messing around myself, I can't seem to convert a void*'s target (which is a string) to a std::string. I've tried using sprintf(buffer, "%p", *((int *)point));
as recommended by this page to get to a C string, but to no avail. And sadly, yes, I have to use a void*, as that's what SDL uses in their USEREVENT struct.
The code I'm using to fill the Userevent, for those interested, is:
std::string filename = "ResumeButton.png";
SDL_Event button_press;
button_press.type = BUTTON_PRESS;
button_press.user.data1 = &filename;
SDL_PushEvent(&button_press);
Any ideas?
EDIT: Thanks for all the responses, I just needed to cast the void* to a std::string*. Silly me. Thank you guys so much!
