PTHREAD_SINGLE_NP(3) BSD Programmer's Manual PTHREAD_SINGLE_NP(3)
pthread_single_np, pthread_multi_np - switch thread scheduling mode
#include <pthread.h>
#include <pthread_np.h>
int
pthread_single_np(void);
int
pthread_multi_np(void);
The pthread_single_np() function causes the process to enter single-
threaded (non-POSIX) scheduling mode.
The pthread_multi_np() function causes the process to return to multi-
threaded scheduling mode.
The pthread_single_np() and pthread_multi_np() functions return zero on
success, or an error number on failure.
pthreads(3)
The pthread_single_np() and pthread_multi_np() functions are non-portable
and may not be supported with the above semantics on other POSIX systems.
