OSErr FSGetForkSize ( SInt16 forkRefNum, SInt64 *forkSize );
The reference number of the fork
On return, a pointer to the logical size of the fork, in bytes. The size returned is the total number of bytes that can be read from the fork; the amount of space actually allocated on the volume (the physcial size) will probably be larger.
