3.39 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:logical function omp_test_lock(svar)
integer(omp_lock_kind), intent(inout) :: svar
