8 | The library part is distributed under LGPLv2.1 or later. See lgpl-2.1.txt for |
| 9 | details. This applies to : | |
| 10 | ||
| 11 | urcu.h | |
| 12 | urcu.c | |
| 13 | urcu-static.h | |
| 14 | arch_x86.h | |
| 15 | arch_ppc.h | |
| 16 | ||
| 17 | LGPL-compatible source code can statically use the library header using : | |
| 18 | ||
| 19 | #define _LGPL_SOURCE | |
| 20 | #include <urcu.h> | |
| 21 | ||
| 22 | Dynamic-only linking with the LGPL library is used if _LGPL_SOURCE is not | |
| 23 | defined. It permits relinking with newer versions of the library, which is | |
| 24 | required by the LGPL license. | |
