h1. osmo_io

@osmo_io@ is the new way of ho we do I/O in osmocom projects. It moves from a raw select/poll abstraction (where every application performs its own read/write once the fd becomes readble/writable) to a submission/completion model, where the actual I/O is performed by the library, an the application just submits write requests (as @struct msgb@) and receives write-completion and read-completion call-backs.

For more information, see: FIXME
