omp_unset_lock – Unset simple lock

Description:

A simple lock about to be unset must have been locked by omp_set_lock or omp_test_lock before. In addition, the lock must be held by the thread calling omp_unset_lock. Then, the lock becomes unlocked. If one or more threads attempted to set the lock before, one of them is chosen to, again, set the lock to itself.

C/C++:

Prototype:

void omp_unset_lock(omp_lock_t *lock);

Fortran:

Interface:	subroutine omp_unset_lock(svar)
	integer(omp_lock_kind), intent(inout) :: svar
