Method of isolating a memory location containing an obsolete value |
摘要 |
A method of isolating a memory location containing an obsolete value of a variable, in a shared memory of a computer, said location being referenced via a pointer for access in the context of a first transaction, a lock called a "hold" being placed on said location and being assigned to a single task, said hold preventing any other task from accessing said location. The method of the invention does not free the location containing the obsolete value, but it isolates it from transactions other than that transaction which possesses the first pointer. This allows the task owning the first pointer to continue to access said obsolete value. However, any transaction can access another value of the variable, without waiting, because the descriptor of said variable directs said transactions to a location which is freely accessible and contains said other value.
