It can't be in the intrcheck.c file since that file (and the whole directory it is in) doesn't know about objects or exceptions. It can't be in errors.c because it can be overridden (at link time) by a more powerful version implemented in signalmodule.c. */ #include "Python.h" /* ARGSUSED */ int PyErr_CheckSignals(void) { if (!PyOS_InterruptOccurred()) return 0; PyErr_SetNone(PyExc_KeyboardInterrupt); return -1; }
