Heh, I just asked Gemini (2.5 Flash) that question, and it responded
with an intelligent-looking answer along with code that almost always
(but not always) works and which contained this stylistic howler:
volatile sig_atomic_t in_signal_handler = 0;
void my_signal_handler(int signum) {
in_signal_handler = 1;
}
... and of course examining in_signal_handler does not tell you whether
the currently executing thread is in a signal handler.
Anyway, I suppose I should limit my use of genAI when writing detailed
technical documentation.
