  42  * These functions are complementary to the standard JNI support.

  44  *
  45  * First, this file contains the VM-related functions needed by native
  46  * libraries in the standard Java API. For example, the java.lang.Object
  47  * class needs VM-level functions that wait for and notify monitors.
  48  *
  49  * Second, (included from jvm_constants.h) constant definitions
  50  * needed by the byte code verifier and class file format checker.
  51  * These definitions allow the verifier and format checker to be written
  52  * in a VM-independent way.
  53  *
  54  * Third, this file contains various I/O and network operations needed
  55  * by the standard Java I/O and network APIs. A part of these APIs,
  56  * namely the jio_xxxprintf functions, are included from jvm_io.h.
