/* This header is used during the build process to find the size and
|
|
alignment of the public OpenMP locks, so that we can export data
|
|
structures without polluting the namespace.
|
|
|
|
In this default POSIX implementation, we used to map the two locks to the
|
|
same PTHREADS primitive, but for OpenMP 3.0 sem_t needs to be used
|
|
instead, as pthread_mutex_unlock should not be called by different
|
|
thread than the one that called pthread_mutex_lock. */
