The FPC runtime library seems to export the type definitions of pthread_mutex_t and pthread_cond_t but the functions that operate on them are private in cthreads.pp and pthread.inc.

So, is there a Pascal runtime library equivalent of the following code or should I redeclare the required C-functions ?

var
mutex: pthread_mutex_t;
condition: pthread_cond_t;
thread 1
------
pthread_mutex_lock( mutex);
while not condition do
     pthread_cond_wait( condition, mutex);
pthread_mutex_unlock( mutex);
thread 2:
------
pthread_mutex_lock( mutex);
pthread_cond_signal( condition);
pthread_mutex_unlock( mutex);

There is a pthreads library interface in the pthreads unit (packages/pthreads).
