open-file and fd->*port Lassi Kortela 10 Sep 2020 16:05 UTC

A child process using a known fd number (e.g. 3) from its parent (or from its predecessor before execve()) is a good convention for IPC. Hence it ought to be a useful feature to open a known fd as a Scheme port. If some C API outside SRFI 170 returns an fd, being able to turn that into a Scheme port is also good. If open-file takes an integer (giving the fd) how would it interpret its flags argument?
