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.

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. MirBSD #10-current March 21, 1999 1
