| 2 | /* C objects to be exported from one extension module to another. | |
| 3 | ||
| 4 | C objects are used for communication between extension modules. | |
| 5 | They provide a way for an extension module to export a C interface | |
| 6 | to other extension modules, so that extension modules can use the | |
| 7 | Python import mechanism to link to one another. | |
