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.
