33 | .SH DESCRIPTION | |
34 | .I Getmntinfo | |
35 | returns an array of | |
36 | .I statfs | |
37 | structures describing each currently mounted file system (see | |
38 | .IR statfs (2)). | |
39 | .SH DIAGNOSTICS | |
40 | On successful completion, | |
41 | .I getmntinfo | |
42 | returns a count of the number of elements in the array. | |
43 | The pointer to the array is stored into | |
44 | .IR mntbufp . | |
45 | Otherwise, zero is returned and | |
46 | .I mntbufp | |
47 | is unmodified. | |
48 | .SH BUGS | |
49 | All information is contained in a static area, | |
50 | so it must be copied if it is to be saved. | |
