/* Note: In addition to this header file AccessBridgeCalls.c must be compiled and

 * Bridge API and also hides the complexities associated with interfacing to the
 * associated Java Access Bridge DLL which is installed when Java is installed.
 *
 * AccessBridgeCalls.c is available for download from the OpenJDK repository using
 * the following link:
 *
 * http://hg.openjdk.java.net/jdk9/jdk9/jdk/raw-file/tip/src/jdk.accessibility/windows/native/bridge/AccessBridgeCalls.c
 *
 * Also note that the API is used in the jaccessinspector and jaccesswalker tools.
 * The source for those tools is available in the OpenJDK repository at these links:
 *
 * http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/src/jdk.accessibility/windows/native/jaccessinspector/jaccessinspector.cpp
