That's what I found so confusing about the opengl docs. Just 
guessing here but char* is a pointer to the first char in the 
string, then what exactly is char**? Is it pointing to the first 
char of the first string in an array?

Does C/D just scrub through memory until it finds the end of an 
array? Also what signifies an end of array, or any other 
keypoints?

aaaaahh I have so many questions O_o
