/*
 * The purpose of this header file is to create "fake" definitions for
 * Posix Threads routines used by RM/OpenRM. This header file is included
 * from RM/OpenRM code if the compile flag -D_NO_PTHREADS is set. If
 * _NO_PTHREADS is set, RM/OpenRM will not support multithreaded rendering,
 * and is not guaranteed to support thread-safe operation (read or write
 * access to the scene graph by multiple application threads).
 *
 * According to the pthreads man pages:
 * 1. mutexes - pthread_mutex_init always returns 0, other mutex routines
 *    return 0 on success and 1 on failure.
 * 2. cond variables - all condition variable routines return 0 on success
 *    and 1 on failure. pthread_cond_init never returns an error.
