Edit: npy_interrupt.h
/* * 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). */ #ifndef NUMPY_CORE_INCLUDE_NUMPY_NPY_INTERRUPT_H_ #define NUMPY_CORE_INCLUDE_NUMPY_NPY_INTERRUPT_H_ #ifndef NPY_NO_SIGNAL #include <setjmp.h> #include <signal.h> #ifndef sigsetjmp #define NPY_SIGSETJMP(arg1, arg2) setjmp(arg1) #define NPY_SIGLONGJMP(arg1, arg2) longjmp(arg1, arg2) #define NPY_SIGJMP_BUF jmp_buf #else #define NPY_SIGSETJMP(arg1, arg2) sigsetjmp(arg1, arg2) #define NPY_SIGLONGJMP(arg1, arg2) siglongjmp(arg1, arg2) #define NPY_SIGJMP_BUF sigjmp_buf #endif # define NPY_SIGINT_ON { \ PyOS_sighandler_t _npy_sig_save; \ _npy_sig_save = PyOS_setsig(SIGINT, _PyArray_SigintHandler); \ if (NPY_SIGSETJMP(*((NPY_SIGJMP_BUF *)_PyArray_GetSigintBuf()), \ 1) == 0) { \ # define NPY_SIGINT_OFF } \ PyOS_setsig(SIGINT, _npy_sig_save); \ } #else /* NPY_NO_SIGNAL */ #define NPY_SIGINT_ON #define NPY_SIGINT_OFF #endif /* HAVE_SIGSETJMP */ #endif /* NUMPY_CORE_INCLUDE_NUMPY_NPY_INTERRUPT_H_ */
