Thanks, I was searching some outdated source. Currently, <rte_os_shim.h> contains at least `read()`, `write()`, and `unlink()` which POSIX places in <unistd.h>. I wonder whether all that stuff should be moved into EAL's <unistd.h> or, on the opposite, <rte_os_shim.h> should consume all other shims. But that would be a broader refactoring, so for the fix: Acked-by: Dmitry Kozlyuk <[email protected]>
