--- received arguments ---
PK_THREAD_exclusion_t        clear,          --- type of exclusion to clear

--- returned arguments ---
PK_THREAD_exclusion_t *const exclusion,      --- type of thread exclusion
PK_LOGICAL_t          *const was_this_thread --- whether the calling thread

)


This function tries to clear an exclusion that may be preventing other threads
from entering Parasolid.


Specific Errors:
    PK_ERROR_bad_thread     Calling thread did not cause exclusion
    PK_ERROR_fatal_error    Cannot clear a fatal error


If clearing the exclusion was successful then 'exclusion' will be set to
PK_THREAD_exclusion_none. Otherwise, if the calling thread is not the thread
that caused the exclusion then 'was_this_thread' will be set to
PK_LOGICAL_false.

The value of 'clear' must be PK_THREAD_exclusion_serious_c. Fatal
exclusions cannot be cleared using this function.

This function can only be called when the modeller is started.
