Hi,
I use FreeBSD 9.0 Beta2.
When I use sctp_connectx to init a new association , the return value of
this function is strange.
The return value is not any of following:1.EINVAL, 2.E2BIG, 3.EBADOF,
4.ENOTSOCK.
I use perror() function to see detail, it shows that " Resource temporarily
unavailable
First, I use the return value of sctp_connectx, and I do not use errno, so
the return value does not match the errors gived in manual. Now,I know it is
my mistake.
However, I write a simple program to test sctp_connectx, it still show
error.The errno is "EINVAL", I am sure that the paraments are s
Hi, Michael
The problem about sctp_connectx is solved.Thank you very much.
But I encounter another problem, it's about sctp_getladdrs().Every time I
call this function, the return value is "ENOMEM". Even I reboot the
computer, this problem still exists.
My function is:
struct sockaddr*show_ip
Sorry.The return value is -1, that means sctp_getladdrs() and
sctp_getpaddrs() encounter an error. And the errno is set to ENOMEM.

Before testing cmt in wlan,we also turn on sysctl states by setting
sysctl net.inet.sctp.cmt_pf=1
sysctl net.inet.sctp.cmt_use_dac=1
sysctl net.inet.sctp.cmt_on_off=1
My Os is Freebsd8.2, I write a simple tarball to send data , and get data

They are in different band.I am sure about that.
