ENOTSOCK

[David Michael]

Hi,

A few of the socket-related functions in glibc don't seem to return
ENOTSOCK.  Would it be more "correct" to return this as opposed to
EMIG_BAD_ID?  In particular, can at least send() be made to return
ENOTSOCK for PulseAudio compatibility?  The following example uses
both MIG_BAD_ID and EOPNOTSUPP as some other functions do, although
I've only seen it return EMIG_BAD_ID.

Thanks.

David
