POSIX can't suspend pthread?

[DJMaze]

Everywhere i look i can't find the default implementation of pthread_suspend in POSIX.
It seems many pthread.h implementations have pthread_suspend() but not the opengroup.org one (which is used by linux), so i'm holding back untill i get some confirmations.

I want to know since one of my Win32 API functions runs a thread that recursively reads files from the harddisk. A dialog has 2 buttons: Cancel and Pause.
By clicking [Pause] it suspends the thread and waits till the user wants to continue or cancels.

Win32 has functions for this but i can't find it in pthread.
Someone has a clue or should i wrap around my own variable like

PHP Code:

while (!suspended) {
} 


or a mutex

PHP Code:

pthread_cond_wait(pthread_cond_t *, pthread_mutex_t *);

Wait on a condition variable.

pthread_suspend is not portable (and probably isn't POSIX). pthread_suspend probably wraps a call to pthread_cond_wait to a single function.

You can always write your own pthread_suspend and use that to make things more modular.

I realize this is a fairly old topic, but noone seems to have touched it.
