Nothing, except that calling a system command from C when you can roll your own method in about 18 lines of code is usually not ideal. Particularly when speed is important. And yes, it is definitely important - disk access can be an insurmountable bottleneck for high volume systems if it is neglected at the implemenation stage. I only wanted a system lib call because I trust FreeBSDs implementation to be faster than my quick throw together. I've already written it. It's not pretty, and probably not as fast as a system lib would be (it has to make 1 system call per directory in the path, rather than just one system call for the whole path). It is, however, much faster than a call to system() would be.
