int
getmntinfo(struct
statfs **mntbufp, int
flags);
getmntinfo() function returns an array of
statfs structures describing each currently mounted file
system (see statfs(2)).
The getmntinfo() function passes its
flags parameter transparently to
getfsstat(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 getfsstat(2) or
malloc(3).
getmntinfo() function first appeared in
4.4BSD.
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.
