/*
* This API is only provided because it is part of publicly exported
* headers. Its use is considered DEPRECATED, and it will be removed
* eventually.
* (This includes the _PyArray_SigintHandler and _PyArray_GetSigintBuf
* functions which are however, public API, and not headers.)
*
* Instead of using these non-threadsafe macros consider periodically
* querying `PyErr_CheckSignals()` or `PyOS_InterruptOccurred()` will work.
* Both of these require holding the GIL, although cpython could add a
* version of `PyOS_InterruptOccurred()` which does not. Such a version
* actually exists as private API in Python 3.10, and backported to 3.9 and 3.8,
* see also https://bugs.python.org/issue41037 and
* https://github.com/python/cpython/pull/20599).
