C library re-entrancy under Zephyr

Rob Meades

Should I expect C library functions (e.g. strtok()) under Zephyr to be re-entrant or must I call the re-entrant versions (i.e. in this case strtok_r())?

I ask because I am building/running nRF52840 (cortex-m4) and strok() _appears_ to NOT be re-entrant: I'd like to understand if this is expected or if I've messed up a configuration somewhere. My prj.conf file is attached in case it is helpful in answering the question.
