Manual Pages  — PTHREAD_SUSPEND_ALL_NP

NAME

pthread_suspend_all_np – suspend all active threads

CONTENTS

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)
