/* Capsule objects let you wrap a C "void *" pointer in a Python
|
|
object. They're a way of passing data through the Python interpreter
|
|
without creating your own custom type.
|
|
|
|
Capsules are used for communication between extension modules.
|
|
They provide a way for an extension module to export a C interface
|
|
to other extension modules, so that extension modules can use the
|
|
Python import mechanism to link to one another.
|
|
|
|
For more information, please see "c-api/capsule.html" in the
|
|
documentation.
