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

     pthread_resume_all_np(3), pthread_suspend_all_np(3)

PTHREAD_ATTR_SETCREATESUSPEND_NP(3)			   BSD Library Functions Manual 		       PTHREAD_ATTR_SETCREATESUSPEND_NP(3)

NAME

     pthread_attr_setcreatesuspend_np -- prepare attribute for creation of suspended thread

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread_np.h>

     int
     pthread_attr_setcreatesuspend_np(pthread_attr_t *attr);

DESCRIPTION

     The pthread_attr_setcreatesuspend_np() instructs pthread_create(3) that the thread created with the attr attribute should be created and left
     in a suspended state until explicitly resumed by the call to pthread_resume_np() or pthread_resume_all_np().

RETURN VALUES

     The pthread_attr_setcreatesuspend_np() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable
     errno is set to indicate the error.

ERRORS

     The pthread_attr_setcreatesuspend_np() function will fail if:

     [EINVAL]		The value specified by attr is invalid.
