[MacRuby-devel] Pointer to memory. was: Pointers for BOOL types

[Dave Lee]

try "^v". ^ is pointer, v is void.

If you look at the .bridgesupport file, in this case
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/BridgeSupport/CoreGraphicsFull.bridgesupport,
you'll see the the objc types listed for the various functions,
structs, etc.
