Method Detail

getHandle

public static int getHandle(FileDescriptor descriptor)

setHandle

public static void setHandle(FileDescriptor descriptor,
                             int handle)

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.nativeimage.c.type.CCharPointer bytes,
                                 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.
