Class EXTWin32KeyedMutex

java.lang.Object

org.lwjgl.opengles.EXTWin32KeyedMutex

public class EXTWin32KeyedMutex
extends java.lang.Object

Native bindings to the EXT_win32_keyed_mutex extension.

Direct3D image objects may have a built-in synchronization primitive associated with them that can be used to synchronize access to their contents across process and API boundaries. This extension provides access to that synchronization primitive via two new commands that operate on GL memory objects.

Requires EXT_memory_object.

Method Detail

glAcquireKeyedMutexWin32EXT

public static boolean glAcquireKeyedMutexWin32EXT(int memory,
                                                  long key,
                                                  int timeout)

Blocks GL command processing until a keyed mutex is acquired.

Parameters:

memory - identifies which keyed mutex to acquire

key - is the mutex value to wait for

timeout - the time, in milliseconds, to wait before failing the acquire operation

glReleaseKeyedMutexWin32EXT

public static boolean glReleaseKeyedMutexWin32EXT(int memory,
                                                  long key)

Releases a keyed mutex after all prior GL command processing has completed.

Parameters:

memory - identifies the keyed mutex to release

key - the mutex value set by the release operation
