| 60 | This header provides access to cStringIO objects from C. |
| 61 | Functions are provided for calling cStringIO objects and |
| 62 | macros are provided for testing whether you have cStringIO |
| 63 | objects. |
| 64 | |
| 65 | Before calling any of the functions or macros, you must initialize |
| 66 | the routines with: |
| 67 | |
| 68 | PycStringIO_IMPORT |
| 69 | |
| 70 | This would typically be done in your init function. |
