Subject: Linux should define ENOTSUP
Date: Wed, 6 Dec 2006 14:51:34 +0100	[thread overview]
Message-ID: <20061206135134.GJ3927@implementation.labri.fr> (raw)

Hi,

ENOTSUP is not used at all by linux (though it is defined for parisc),
while as susv3 specifies, ENOTSUP shall be different than EOPNOTSUPP.
Is there a reason for doing so? (except history)

Currently, code like

switch(errno) {
	ENOTSUP:
		foo();
		break;
	EOPNOTSUP:
		bar();
		break;
}
just can't compile...

Is there any way to fix this?  Glibc people don't seem to want to fix it
on their part, see
http://sources.redhat.com/bugzilla/show_bug.cgi?id=2363
