pycapsule.h

/* 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.
