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
|
|
|
|
This would typically be done in your init function.
