13<h3>PARAMETERS</h3>
14<dl>
15<p>
16<dt> <var>host</var> 
17<dd>
18[in host-name send right]
19The name (or control) port for the host for 
20which information is to be obtained.
21<p>
22<dt> <var>flavor</var> 
23<dd>
24[in scalar]
25The type of statistics desired:
26<dl>
27<p>
28<dt> <strong>HOST_BASIC_INFO</strong>
29<dd>
30Basic information (number of processors, amount of
31memory).  The returned structure is <strong>host_basic_info</strong>.
32<p>
33<dt> <strong>HOST_SCHED_INFO</strong>
34<dd>
35Basic restrictions of the kernel's scheduling, minimum
36quantum and time-out value.  The returned structure is 
37<strong>host_sched_info</strong>.
38<p>
39<dt> <strong>HOST_RESOURCE_SIZES</strong>
40<dd>
41This interface feature is not implemented in OSF/1 R1.3.
42Size of significant kernel structures, as a ledger would
43consider them when limiting kernel resource consumption.  The
44returned structure is <strong>kernel_resource_sizes</strong>.
45</dl>
46<p>
47<dt> <var>host_info</var> 
48<dd>
49[out structure]
50Statistics about the specified host.
51<p>
52<dt> <var>host_info_count</var> 
53<dd>
54[in/out scalar]
55On input, the maximum size of the buffer; on output, the 
56size returned (in natural-sized units).
57</dl>
58<h3>DESCRIPTION</h3>
59<p>
60The <strong>host_info</strong> function returns selected information
61about a host, as specified 
62by <var>flavor</var>.
63<h3>NOTES</h3>
64<p>
65This interface is machine word length specific because of the memory size
66returned by <strong>HOST_BASIC_INFO</strong>.
67<h3>RETURN VALUES</h3>
68<p>
69Only generic errors apply.
