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)
