sem_xxxx APIs

QNX implemented POSIX APIs, but how does sem_xxxx APIs got implemented.

Does sem_xxxx routines actually send message to a "semaphore resource manager"? How expansive if it is sending messages 
all the time, if an application
calling sem_open, follow by sem_wait, follow by sem_post, and then sem_close all the time.
