problem in using sendmsg()

[anil akkur]

Hi,
I am using Free BSD version 5.0.
I am getting the error message (EINVAL) when I use sendmsg().
I am initialising all the values of structure msghdr .

the code looks likes,

  struct msghdr msg ;
  int send_sock ;


/* then I am initialising structure msg */

/* Then calll the sendmessage with arguments */

sendmsg(send_sock, &msg, flag) ;

/* i used all the values for flag each time */

When it is executed errno is setting to 22.

I am not getting the where the fault is .

plz help me in getting this solved .

thanks in advance ,


with warm regards,
Anil Akkur
