NAME
     pthread_single_np, pthread_multi_np - switch thread scheduling mode

SYNOPSIS
     #include <pthread.h>
     #include <pthread_np.h>

     int
     pthread_single_np(void);

     int
     pthread_multi_np(void);

DESCRIPTION
     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.

RETURN VALUES
     The pthread_single_np() and pthread_multi_np() functions return zero on
     success, or an error number on failure.

SEE ALSO

STANDARDS
     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.
