2.13 omp_test_lock – Test and set simple lock if available

Description:

Before setting a simple lock, the lock variable must be initialized by omp_init_lock. Contrary to omp_set_lock, omp_test_lock does not block if the lock is not available. This function returns true upon success,false otherwise. Here, true and false represent their language-specific counterparts.

C/C++:

Prototype:

int omp_test_lock(omp_lock_t *lock);

Fortran:

Interface:	subroutine omp_test_lock(lock)
	logical(omp_logical_kind) :: omp_test_lock
	integer(omp_lock_kind), intent(out) :: lock
