14 struct statfs **mntbufp;
15 int flags

18 The getmntinfo() function returns an array of statfs structures
19 describing each currently mounted file system (see statfs(2).
20
21 The getmntinfo() function passes its flags parameter transparently to
22 getfsstat(2).
23
25 On successful completion, getmntinfo() returns a count of the number of
26 elements in the array. The pointer to the array is stored into mnt‐
27 bufp.
28
29 If an error occurs, zero is returned and the external variable errno is
30 set to indicate the error. Although the pointer mntbufp will be unmod‐
31 ified, any information previously returned by getmntinfo() will be
32 lost.
33
35 The getmntinfo() function may fail and set errno for any of the errors
36 specified for the library routines getfsstat(2) or malloc(3).

42 The getmntinfo() function first appeared in 4.4BSD.
43
45 The getmntinfo() function writes the array of structures to an internal
46 static object and returns a pointer to that object. Subsequent calls to
47 getmntinfo() will modify the same object.
48
49 The memory allocated by getmntinfo() cannot be free(2)'d by the appli‐
50 cation.
