29 * simple netstat based on snmp/mib-2 interface to the TCP/IP stack
30 *
31 * NOTES:
32 * 1. A comment "LINTED: (note 1)" appears before certain lines where
33 * lint would have complained, "pointer cast may result in improper
34 * alignment". These are lines where lint had suspected potential
35 * improper alignment of a data structure; in each such situation
36 * we have relied on the kernel guaranteeing proper alignment.
37 * 2. Some 'for' loops have been commented as "'for' loop 1", etc
38 * because they have 'continue' or 'break' statements in their
39 * bodies. 'continue' statements have been used inside some loops
40 * where avoiding them would have led to deep levels of indentation.
41 *
42 * TODO:
43 * Add ability to request subsets from kernel (with level = MIB2_IP;
44 * name = 0 meaning everything for compatibility)
