Does anyone know of a way to do this? I am trying to pull information
about the CPU, Memory and Disk. I have the CPU and memory down, but I
can't find info anywhere on how to pull this short of writing a script
for df, which I don't want to do.

Any thoughts?

- Get the source for df, and see what it calls

FSGetVolumeInfo will fill out a FSVolumeInfo structure. These fields in
that structure are of interest:

UInt32 blockSize;
UInt32 totalBlocks;
UInt32 freeBlocks;
