Method Detail

PID

public static int PID()

Get the process ID of the Java Virtual Machine. The process ID has been pre-fetched, so there is no overhead cost in repeated accesses to its value. If the library implementing the native method that provides the interface to the getpid system function did not load successfully, then the return value will be zero.

Returns:

The process ID (PID) of the JVM running this class. This will be zero if the native getpid system function could not be accessed because the NATIVE_METHODS_LIBRARY_NAME library failed to load.
