dtrace problem with sendmsg
Oct 22, 2012 1:07 AM
Currently Being Moderated
I try to display the content of the sendmsg buffer:
/execname == "msgsend"/
self->msghdr = arg1;
msghdrp = (struct msghdr *)copyin(self->msghdr, sizeof(struct
printf("msghdr namelen is %d\n",msghdrp->msg_namelen);
the value printed for namelen is not the expected one but in fact the
value of the following
field in the msghdr structure : the address of msg_iov.
I must be missing something but don't know what.
