The <function>sg_get_fs_stats</function> takes a pointer to an |
| 38 |

int, <parameter>entries</parameter>, which is filled with the |
| 39 |
tdb |
1.2 |
number of mounted file systems the machine has. The return |
| 40 |
|
|
value is a pointer to the first member of an array of |
| 41 |
|
|
<structname>sg_fs_stats</structname> structures; the number of |

tdb |
1.3 |
entries in the array is returned in <parameter>entries</parameter>. |
