Answering my own question for the benefit of anyone listening who didn’t already know: the answer is that the built-in minimal C library offers some functions re-entrantly and, if you chose to use new

Just to be clear on this, is it true that re-entrancy is not supported by Zephyr for any of the newlib stdio.h or stdlib.h functions, so not just the likes of strok() but also snprintf() and, more fun

Thanks for the swift response. That's a shame. I will go look at the PR at your link as shifting to the re-entrant versions just for Zephyr is going to be painful. Rob

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 (c

I would like to add a linker option (-Xlinker --wrap=blah) to my Zephyr build, without editing the main Zephyr files, just append some to the usual linker options for my specific build. How would I go

I have a question about heap usage monitoring. Apologies if this is the wrong place to ask, please feel free to point me elsewhere if that is the case. I'm using Zephyr on a Nordic NRF53 chip and I ne
