PTHREAD_SUSPEND_ALL_NP(3)                     FreeBSD Library Functions Manual

NAME
     pthread_suspend_all_np - suspend all active threads

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread_np.h>

     void
     pthread_suspend_all_np(void);

DESCRIPTION
     The pthread_suspend_all_np() function causes all active threads to be
     suspended.  The only exception is the current thread, the thread that
     called the pthread_suspend_all_np() function.

     It is not safe for the caller of the pthread_suspend_all_np() function to
     use any non-async signal safe functions, besides
     pthread_resume_all_np(3), until threads are resumed, unless measures are
     taken to ensure that all threads are suspended at safe points.

SEE ALSO
     pthread_np(3), pthread_resume_all_np(3), pthread_resume_np(3),
     pthread_suspend_np(3)
