What's wrong with writefln("%s", glGetString(GL_EXTENSIONS));

printf works but not writefln?

How can I get the returned string by GLubyte* glGetString(); into a D 
char[]?

:) I hope I've expressed myself clear enough. Sorry if I've just wrote 
incomprehensible garbage.

std.string.toString:

writefln("%s", toString(glGetString(GL_EXTENSIONS)));

Given that its natural type is ubyte* you should be able to do this:

# private import std.string ;
#
# char[] toString (ubyte* foo) {
#   return std.string.toString(cast(char*) foo);
# }

I would think so, anyhow.  If it will not allow a direct cast to char*, you can
always add 
a middle state cast to void* first.

Thank you, Chris,

I think this will work for me.
