NAME    [Toc]    [Back]

     pthread_multi_np, pthread_single_np -- switch between multi- and singlethreaded
 scheduling modes

LIBRARY    [Toc]    [Back]

     Reentrant C Library (libc_r, -lc_r)

SYNOPSIS    [Toc]    [Back]

     #include <pthread_np.h>

     int
     pthread_multi_np(void);

     int
     pthread_single_np(void);

DESCRIPTION    [Toc]    [Back]

     The pthread_single_np() function switches the process to a singlethreaded
 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    [Toc]    [Back]

     The pthread_multi_np() and pthread_single_np functions always return 0.

SEE ALSO    [Toc]    [Back]

     pthread_resume_all_np(3), pthread_suspend_all_np(3)
