SYNOPSIS


.In 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).

IMPLEMENTATION NOTES

The pthread_single_np function is only available in
.Lb libc_r and
.Lb libpthread . This function is not implemented in
.Lb libthr .

RETURN VALUES

The pthread_multi_np and pthread_single_np functions always return 0.
