Subject: strtok


we are working on an OS for a STM32 MCU. We like how the reentrancy is solved in musl, but ... when two (or more) userspace programs using a strtok function are run, there might be a collision (because strtok uses a static var to save the pointer). We did not find any redirection mechanism from strtok to strtok_r. How is it meant pls? We do not want to force the users to write strtok_r into a non-threaded user program.

Is there some solution to make it work right?

Thank you
