NAME

pthread_single_np —
switch between multi- and single-threaded scheduling modes

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.
