First of all, if you are using an IrDA stack without my
patches, you are asking for trouble. The latest official stack from
Dag contains the preliminary support for IRLMP_IAS_SET that I wrote,
but you *really* need my patch you you want to avoid troubles.
My patch my be found there :
http://www.hpl.hp.com/personal/Jean_Tourrilhes/IrDA/Java.html
More recent versions for 2.4 :

Dag told me that he was planning to integrate those patches in
the official IrDA stack, so maybe he can give you more info on the
subject.
Now, a sample program do exist to show you how to use this
stuff, and it was in fact part of my test suite. I did post it ages
ago on the list, and I hope that Dag will include it in the sample
directory of irda-utils sometimes (along with other useful sample
programs that I did).
Currently, this program is available in a subdirectory of the
Java-IrDA package, called irdaspray.magic.c. Check the tar file for
details (url above). Maybe I should bring those programs closer to the
surface...
Anyway, to set a string in IAS, it look likes :
---------------------------------------
struct irda_ias_set ias_query;
/* Set a string in IAS */
strcpy(ias_query.irda_class_name, "my:object");
ias_query.irda_attrib_type = IAS_STRING;
strcpy(ias_query.irda_attrib_name, "my:string");
strcpy(ias_query.attribute.irda_attrib_string.string, "The String");
ias_query.attribute.irda_attrib_string.len = strlen("The String");
if (setsockopt(fd, SOL_IRLMP, IRLMP_IAS_SET, &ias_query,
sizeof(ias_query)))
{
perror("setsockopt");
exit(-1);
}
---------------------------------------
I looked at your code, and honestly it gives me headackes
because it's to ugly. You are playing with arrays and pointers in
weirds ways instead of getting things straight. I mean, compare your
code and mine !
Anyway, your error is trivial. The error is returned by the
following line in net/irda/af_irda.c (line 1761 in my source) :
-----------------------
if (optlen != sizeof(struct irda_ias_set))
return -EINVAL;
-----------------------
By the way, I'm curious at what you are doing. I originally
implemente IAS support for something very similar.
Have fun, and good luck in debugging...
Jean
