  getmntinfo(struct
    statvfs **mntbufp, int
    flags);
getmntinfo() function returns an array of
  statvfs structures describing each currently mounted file
  system (see statvfs(2)).
The getmntinfo() function passes its
    flags parameter transparently to
    getvfsstat(2).
getmntinfo() returns a count
  of the number of elements in the array. The pointer to the array is stored
  into mntbufp.
If an error occurs, zero is returned and the external variable
    errno is set to indicate the error. Although the
    pointer mntbufp will be unmodified, any information
    previously returned by getmntinfo() will be
  lost.
getmntinfo() function may fail and set
  errno for any of the errors specified for the library
  routines getvfsstat(2) or
  malloc(3).
getmntinfo() function first appeared in
  4.4BSD. It was converted from using
  getfsstat() to
  getvfsstat(2) in
  NetBSD 3.0.
getmntinfo() function writes the array of structures
  to an internal static object and returns a pointer to that object. Subsequent
  calls to getmntinfo() will modify the same object.
The memory allocated by getmntinfo()
    cannot be free(3)'d by the
    application.
