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.

“ A typical Unix /bin or /usr/bin directory contains a hundred different kinds of programs, written by dozens of egotistical programmers, each with its own syntax, operating paradigm, rules of use ... strategies for specifying options, and different sets of constraints. ”
