| This header provides access to cStringIO objects from C. |
| Functions are provided for calling cStringIO objects and |
| macros are provided for testing whether you have cStringIO |
| objects. |
| |
| Before calling any of the functions or macros, you must initialize |
| the routines with: |
| |
| PycStringIO_IMPORT |
| |
| This would typically be done in your init function. |
