Types

type Bitmap 

type Bitmap struct {
	// contains filtered or unexported fields
}

Implement the Go bitmap type such that the underlying data can easily be copied in and out. NB that we still have to do copies both directions, because cgo runtime restrictions forbid passing to a C function a pointer to a Go-allocated structure which contains a pointer.
