GETMNTINFO(3) |
NAME
getmntinfo — get information about mounted file systems
LIBRARY
Standard C Library (libc, -lc)
DESCRIPTION
The
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).
RETURN VALUES
On successful completion,
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.
ERRORS
The
getmntinfo() function may fail and set
errno for any of the errors specified for the library routines
getvfsstat(2) or
malloc(3).
HISTORY
The
getmntinfo() function first appeared in
4.4BSD. It was converted from using
getfsstat(2) to
getvfsstat(2) in
NetBSD 3.0.
BUGS
The
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.
