THR_EXIT(2) System Calls Manual THR_EXIT(2) NAME thr_exit -- terminate current thread LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <sys/thr.h> void thr_exit(long *state); DESCRIPTION This function is intended for implementing threading. Normal applica- tions should call pthread_exit(3) instead. The thr_exit() system call terminates the current kernel-scheduled thread. If the state argument is not NULL, the location pointed to by the argu- ment is updated with an arbitrary non-zero value, and an _umtx_op(2) UMTX_OP_WAKE operation is consequently performed on the location. Attempts to terminate the last thread in the process are silently ig- nored. Use _exit(2) syscall to terminate the process. RETURN VALUES The function does not return a value. A return from the function indi- cates that the calling thread was the last one in the process. SEE ALSO _exit(2), _umtx_op(2), thr_kill(2), thr_kill2(2), thr_new(2), thr_self(2), thr_set_name(2), pthread_exit(3) STANDARDS The thr_exit() system call is non-standard and is used by 1:1 Threading Library (libthr, -lthr) to implement IEEE Std 1003.1-2001 ("POSIX.1") pthread(3) functionality. HISTORY The thr_exit() system call first appeared in FreeBSD 5.2. FreeBSD 13.2 May 5, 2020 THR_EXIT(2)
