Gedare is not mistaken. Classic tasks can make POSIX thread calls and vice versa.<br>
<br>
Beware the pthreads are defined to exit silently deleting themselves and classic tasks consider this a fatal error.<br>

Also note that you would need to "configure" your application<br>
correctly so that the resources are available to create tasks of both<br>
types, e.g.<br>
#define CONFIGURE_MAXIMUM_TASKS 2<br>
#define CONFIGURE_MAXIMUM_POSIX_THREADS 3<br>
<br>
if you have 2 classic tasks and 3 pthreads.<br>
