NAME

pthread_multi_np, pthread_single_np —

switch between multi- and single-threaded scheduling modes

LIBRARY

POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

#include <pthread_np.h>

int
pthread_multi_np(void);

int
pthread_single_np(void);

DESCRIPTION

The pthread_single_np() function switches the process to a single-threaded mode, i.e., suspends all threads except the current. The semantics of this function is similar to pthread_suspend_all_np(3).

The pthread_multi_np() function switches the process to a multi-threaded mode. The semantics of this function is similar to pthread_resume_all_np(3).

RETURN VALUES

The pthread_multi_np() and pthread_single_np functions always return 0.
