``module.attribute``. The *name* stored in the capsule must match this
string exactly.
This function splits *name* on the ``.`` character, and imports the first

Return the capsule's internal *pointer* on success. On failure, set an
exception and return ``NULL``.
.. note::
If *name* points to an attribute of some submodule or subpackage, this
submodule or subpackage must be previously imported using other means
(for example, by using :c:func:`PyImport_ImportModule`) for the
attribute lookups to succeed.

*no_block* has no effect anymore.
