If one thread in program calls fork(), does the new process duplicate all threads or single thread

The fork subroutine duplicates the parent process, but duplicates only the calling thread; the child process is a single-threaded process. The calling thread of the parent process becomes the initial thread of the child process; it may not be the initial thread of the parent process. Thus, if the initial thread of the child process returns from its entry-point routine, the child process terminates.
