open is as specified in
ISO/IEC 9945:2003 Portable Operating System(POSIX)and The Single UNIX® Specification(SUS) V3,
but with differences as listed below.
Where ISO/IEC 9945:2003 Portable Operating System(POSIX)and The Single UNIX® Specification(SUS) V3 specifies an ENXIO return, a conforming implementation may return either ENXIO or ENODEV. Implementations are encouarged to return ENXIO. [1]
| [1] | As of spring 2004, we don't know of any Linux kernel patches to switch to ENXIO, but we believe that such a kernel patch would be accepted if submitted. |
