61 * First, this file contains the VM-related functions needed by native | |

65 * Second, this file contains the functions and constant definitions | |
66 * needed by the byte code verifier and class file format checker. | |
67 * These functions allow the verifier and format checker to be written | |
68 * in a VM-independent way. | |

70 * Third, this file contains various I/O and nerwork operations needed | |
71 * by the standard Java I/O and network APIs. | |
