Disallow File IO for a process except for FIFOs

How do you start a procedure that can refrain any kind of documents IO (opening / shutting files, developing / removing files, reviewing / creating files, etc), other than to read and also contact pre - developed FIFOs?

(chroot will certainly not function due to the fact that the procedure can burst out of it, yet tinkering / changing the bit and also such is all right)

BTW: I can not change the programs that are being run
