The lack of memory-resident files in C is indeed very annoying. This 
could work:

Open a pipe(2)
write(2) the mpz_out_raw data on pipe[1]
fdopen a stream on pipe[0]
call mpz_inp_raw

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.
