Re: [ssm] IGMPv3/SSM API for Java ?

[Hoerdt Mickael <[e-mail]>]

I voted too. One may take in account that this Java API may depends on 
libc implementation of RFC 3678 to run (which depends on kernel 
implementation too). I'm not sure how java works, but if its the case, 
only glibc starting from 2.3.4 supports it. Does anyone know how the 
java APIs are implemented ? are they overlay of C/C++ ?
