warning: cast from 'thrd_start_t' (aka 'int (*)(void *)') #58
Description
Hello Richard,
During compilation, I am encountering a warning that appears to be caused by a mix of POSIX threads (pthread_*) and C11 threads (<threads.h>).
It seems that some functions expecting int (*)(void *) are being passed to APIs expecting void ()(void *), and vice versa, leading to incompatible function pointer warnings.
Could you advise on the correct threading model to use, or how to resolve this mismatch?

to 'start_function' (aka 'void ()(void *)')
converts to incompatible function type [-Wcast-function-type-mismatch]
