OpenSemaphoreW

com.sun.jna.platform.win32.WinNT.HANDLE OpenSemaphoreW(int access,
                                                       boolean inheritHandle,
                                                       String name)

Opens an existing semaphore.

Parameters:

access - The access rights.

inheritHandle - true if the handle is inherited.

name - The semaphore's name.

Returns:

The handle or null if the handle could not be created.

CreateSemaphoreW

com.sun.jna.platform.win32.WinNT.HANDLE CreateSemaphoreW(com.sun.jna.platform.win32.WinBase.SECURITY_ATTRIBUTES securityAttributes,
                                                         long count,
                                                         long maximumCount,

Creates a new semaphore.

Parameters:

securityAttributes - The security attributes for the created semaphore.

count - The initial count for the semaphore.

maximumCount - The maximum count for the semaphore.

name - The semaphore's name.

Returns:

The handle or null if the handle could not be created.

ReleaseSemaphore

boolean ReleaseSemaphore(com.sun.jna.platform.win32.WinNT.HANDLE handle,
                         long count,
                         Long previousCount)

Releases the semaphore.

Parameters:

handle - The semaphore's handle.

count - The amount with which to increase the semaphore.
