C++: how to check my directory disk space

I have a directory, and I write some files in to that. How to throw the error exception when my directory is full. i.e. there is no disk space

Whether there's sufficient space left is normally not a concern of the directory but of the whole file system. There are things like quotas, which are normally supported by default by any distributor-made standard kernel but which have to be activated first.
So, I guess a call to statvfs() should do it.

An attempt was made to write a file that exceeds the implementation-defined maximum file size or the process' file size limit, or to write at a position past the maximum allowed offset.

The device containing the file referred to by fd has no room for the data.
