Dear Thomas and Michael,

    I'm very appreciate for your help.

    Follow Thomas,I have tried to test the ext_close() by install sctplib-1.0.8/socketapi-2.2.0,and the problem didn't appear any more.perhaps it's  a bug of  sctplib-1.0.7.

    By the way,The latest versions of sctplib/socketapi is sctplib-1.08/socketapi-2.2.0 in www.sctp.de. I can't get the versions of sctplib-1.09/socketapi-2.2.1, because I can't get into the download page.

    Beacuse our project must used in many computers,even must in other company.so we want not always to make install kernel or open the services of SCTP in "setup".Thanks Michael's advice,Once our project's test is finish,we may be use a kernel implementation instead.

   Thank you again!

   

   best wishes!

   owen

Hi,

from a socket API perspective your close() is OK, it should succeed.
However, the setsockopt() call lateron should fail as well as the close
()
call in echo().

So I think it is a bug in the socketapilib.

Can't you use a kernel implementation? Redhat Linux supports SCTP, as
far as I know.

Best regards
Michael

I cannot reproduce the ext_close() problem with the latest versions of
sctplib/socketapi. Try sctplib-1.0.9/socketapi-2.2.1 from http://tdrwww.exp-
math.uni-essen.de/dreibholz/rserpool/#Download .

Note, that you call ext_setsockopt() on "cfd", which is already closed.
Therefore, your program always fails with perror() -> exit(1).


Best regards
