The statgrab library provides a cross-platform interface to getting |
| 118 |
|
system statistics. Each of the function calls returns a structure |
| 119 |
|
containing statistics. See the manual page for each individual |
| 120 |
|
function for more details on usage. |

<function>statgrab_init(void)</function> should be the first |
| 124 |
< |
function you call before you start to use libstatgrab. This |
| 125 |
< |
function on *bsd systems opens up the kernel structures and |
| 126 |
< |
leaves them open for future use. Because of this, any special |
| 127 |
< |
privileges the program has (e.g. setgid kmem) can be dropped |
| 128 |
< |
after this call, and all the libstatgrab calls should continue to |
| 129 |
< |
work. It is therefore a good idea to call |
| 123 |
> |
<function>statgrab_init</function> must be the first |
| 124 |

function you call before you start to use libstatgrab; it performs all |
| 125 |
> |
the one-time initialisation operations that need setuid/setgid |
| 126 |
> |
privileges. For instance, on *BSD it opens a descriptor to be able to |
| 127 |
> |
read kernel structures later on, and on Solaris it reads the device |
| 128 |
> |
mappings that in some cases are only accessible by root (machines with |
| 129 |
> |
a /dev/osa). Once this has run, the other libstatgrab functions no longer |
| 130 |
> |
need elevated privileges. It is therefore a good idea to call |
| 131 |
|
<function>statgrab_drop_privileges</function>, which discards |
| 132 |
|
setuid and setgid privileges, immediately after you call |
| 133 |
|
<function>statgrab_init</function>, unless your application has |
| 139 |
|
non-zero on failure. |
