# Special cases

A few special C types which would normally be represented by a pointer
type in Go are instead represented by a uintptr. Those include:

1. The *Ref types on Darwin, rooted at CoreFoundation's CFTypeRef type.

2. The object types from Java's JNI interface:

	jobject
	jclass
	jthrowable
	jstring
	jarray
	jbooleanArray
	jbyteArray
	jcharArray
	jshortArray

	"cmd/internal/buildid"
