Example #1

	cs := C.CString(filename)
	defer C.free(unsafe.Pointer(cs))

Example #2

File: version.go Project: jimmyfrasche/cairo

	if v == nil {
		return "unknown PDF version"
	}
	return C.GoString(v)
}

Example #3

File: cairo.go Project: mantyr/go-cairo

	return C.GoString(C.cairo_pdf_version_to_string(C.cairo_pdf_version_t(self)))
}

//
//This method should only be called before any drawing operations have been
