47 *
48 * First, this file contains the VM-related functions needed by native

50 * class needs VM-level functions that wait for and notify monitors.
51 *
52 * Second, this file contains the functions and constant definitions
53 * needed by the byte code verifier and class file format checker.
54 * These functions allow the verifier and format checker to be written
55 * in a VM-independent way.
56 *
57 * Third, this file contains various I/O and nerwork operations needed
58 * by the standard Java I/O and network APIs.
