Will return from the signal handler to the C code, which is likely to raise SIGSEGV that are caused by an invalid operation in C code. It makes little sense to catch synchronous errors like SIGFPE or Virtual machine to execute the corresponding Python signal handlerĪt a later point(for example at the next bytecode instruction). Instead, the low-level signal handler sets a flag which tells the Execution of Python signal handlers ¶Ī Python signal handler does not get executed inside the low-level (C) signal Several functions and signalsĪre not available on these platforms. On WebAssembly platforms wasm32-emscripten and wasm32-wasi, signalsĪre emulated and therefore behave differently. SIGCHLD, which follows the underlying implementation.

This module provides mechanisms to use signal handlers in Python. Signal - Set handlers for asynchronous events ¶
