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:
PycString_IMPORT
1996-12-05 19:30:48 -04:00
This would typically be done in your init function.
