The lack of memory-resident files in C is indeed very annoying. This
Open a pipe(2)
write(2) the mpz_out_raw data on pipe
fdopen a stream on pipe
Alternative solution: socket and dup instead of pipe.
Of course this will fail if the raw data is too large. I dont know if
setsockopt would work on a pipe. But it should work on a socket.
