typedef **addtogroup threads C11 thread emulation on top of POSIX threads ****This is a relatively straightforward implementation of the C11 **thread model on top of POSIX threads The main difficulty this presents **is that the thread entry function signature differs between the **two C11 thread returns an< code > int</code > whereas POSIX returns **a< code > void *</code > ****You can find the thread management interfaces through the **documentation of the type ::thrd_t ****remark In addition to POSIX threads this implementation needs **some C11 atomic operations for initialization via ::call_once and **status communication ****struct tss_t tss_t
