The present invention extends to methods, systems, and computer program products for memory pinning through buffer encapsulation. Within a managed execution environment, a wrapper object encapsulates a memory buffer that is to be shared with a native routine executing in a native execution environment. The wrapper object manages operation of a memory manager on a memory heap corresponding to the memory buffer. The wrapper object includes a first function which sets a pin on the memory buffer and returns a pointer identifying the memory buffer. Setting the pin causes the memory manager to cease moving the memory buffer within the memory heap. The wrapper object also includes a second function which releases the pin on the memory buffer.

Memory pinning through buffer encapsulation

The present invention extends to methods, systems, and computer program products for handling synchronous operations by means of asynchronous operations. Upon completion of an asynchronous operation, a state flag is accessed. The state flag indicates whether or not a sync-over-async wrapper/adapter requested execution of the asynchronous operation. The sync-over-async wrapper/adapter is currently blocked awaiting notice of completion of the asynchronous operation. Based on the state flag, results of the asynchronous operation are stored at a location accessible by the sync-over-async wrapper. A completion signal is sent to the sync-over-async wrapper.
