PTHREAD_MULTI_NP(3)					   BSD Library Functions Manual 				       PTHREAD_MULTI_NP(3)

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 seman-
     tics 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.

SEE ALSO
