With the caveat that this isn't portable (or standard), you could open both ends
of a pipe or a socket, associate one ebd with a FILE * that you pass to your
library, and populate the variable yourself by reading from the other end. As
convoluted as this is, it would still be much faster than file I/O and it
wouldn't require having write access to the disk.
