lastErrorString

public static String lastErrorString(String defaultMsg)

Return the error string for the last error, or a default message.

writeBytes

public static boolean writeBytes(int handle,

                                 org.graalvm.word.UnsignedWord length)

Low-level output of bytes already in native memory. This method is allocation free, so that it can be used, e.g., in low-level logging routines.

getNanoCounter

public static long getNanoCounter()

Retrieve a nanosecond counter for elapsed time measurement.
