How do I resize an ext4 partition programmatically?

Question

I want to resize an ext4 partition programmatically in C. I believe I can use libparted to resize the partition, but not the file system? Can anybody point me in the right direction?

which can be found [here](http://git.kernel.org/?p=fs/ext2/e2fsprogs.git;a=summary). — Alex Chamberlain, Jul 12 '12 at 10:31

Use resize_fs().

Take a look here for example of usage:

Thanks! It should be noted `main` of `main.c` does a lot of work prior to calling that function. – Alex Chamberlain Jul 12 '12 at 11:44
