The statgrab library provides a cross platform interface to getting |
| 109 |
|
|
system statistics. Each of the function calls returns a structure |
| 110 |
|
|
containing statistics. See the manual page for each individual |
| 111 |
|
|
function for more details on usage. |

<para> |
| 114 |
|
|
<function>statgrab_init(void)</function> should be the first |
| 115 |
|
|
function you call before you start to use libstatgrab. This |
| 116 |
|
|
function on *bsd systems opens up the kernel structures and |
| 117 |
|
|
leaves them open for future use. Because of this, any special |
| 118 |
|
|
privileges the program has (e.g. setgid kmem) can be dropped |
| 119 |
|
|
after this call, and all the libstatgrab calls should continue to |
| 120 |
|
|
work. |

<para> |
| 123 |
|
|
<function>statgrab_init</function> returns 0 on success, and |
| 124 |
|
|
non-zero on failure. |

The library was originally written to support the i-scream central |
| 128 |
|
|
monitoring system, but has since become a standalone package. It |
| 129 |
|
|
has been ported to work on Linux, FreeBSD, and Solaris. |
