Using the C/C++ Pico SDK, how can I find out which core my code is running on?

(Specifically, I'd like to use lwIP's LWIP_ASSERT_CORE_LOCKED, which requires a thread or core identifier to determine whether it holds the right locks.)

Not sure why I didn't find it the last time around, but there's get_core_num() in pico_platform.
