Quick C question
Hey guys

sorry to bother but I'm coding in C and I came across a symbol that I don't recognize...

Mind you I haven't used C since my first year of university so that's over 2 years ago.. :P

nFrame << 5

What does the "<<" mean/do ?! I can't find it in any of my books!

edit: Bit shift... grrr sorry about that!

I did some searching and found nothing. Perhaps it's a typo?
