Send and Receive Data

The t6sendto(3NSL) routine sends security attributes with a message. The t6recvfrom(3NSL) routine receives a message and its security attributes. When t6new_attr(3NSL) is on, t6recvfrom(3NSL) receives security attributes only when the attributes in new_attrs have changed.

These routines are specific to sockets. For Transport Layer Interface (TLI), use t6last_attr(3NSL) in place of t6recvfrom(3NSL) and t6new_attr(3NSL); and t6set_endpt_default(3NSL) in place of t6sendto(3NSL).
