which function should I use to list all of the FILE SYSTEMS in UNIX??

[Tommy]

I want to make a program to minitor the usages of all of the file systems on
my AIX or Linux systems.
But I will not use shell commands like "df -k" for some FILE SYSTEMS maybe
not mounted and "df -k" will not collect info about that FILE SYSTEM ,so I
want to obtain theses info from system calls or lib functions .

First I want to list all the FILE SYSTEMS on my OS ,which c function should
I use ?

Thanks!

To find out about filesystems currently mounted, check out getmntent()
and friends.

To find out about all filesystems listed in /etc/fstab, whether mounted
or not, check out getfsent() and friends.

These are not POSIX functions, but they're very common - I think
available both in AIX and Linux.
