| af02d47e | 8 | The library part is distributed under LGPLv2.1 or later. See lgpl-2.1.txt for |
| 323baef5 | 9 | license details. Refer to the individual file headers for details. |

| 11 | LGPL-compatible source code can statically use the library header using : | |
| 12 | ||
| 13 | #define _LGPL_SOURCE | |
| 14 | #include <urcu.h> | |
| 15 | ||
| 16 | Dynamic-only linking with the LGPL library is used if _LGPL_SOURCE is not | |
| 17 | defined. It permits relinking with newer versions of the library, which is | |
| 18 | required by the LGPL license. | |
