t_sndreldata - initiate or respond to an orderly release with user data
#include <xti.h> int t_sndreldata(int fd, struct t_discon *discon);
This function is used to initiate an orderly release of the outgoing direction of data transfer and to send user data with the release. The argument fd identifies the local transport endpoint where the connection exists, and discon points to a t_discon structure containing the following members:
struct netbuf udata; int reason; int sequence;
After calling t_sndreldata(), the user may not send any more data over the connection. However, a user may continue to receive data if an orderly release indication has not been received.
The field reason specifies the reason for the disconnection through a protocol-dependent reason code, and udata identifies any user data that is sent with the disconnection; the field sequence is not used.
The udata structure specifies the user data to be sent to the remote user. The amount of user data must not exceed the limits supported by the transport provider, as returned in the discon field of the info argument of t_open(3NSL) or t_getinfo(3NSL). If the len field of udata is zero or if the provider did not return T_ORDRELDATA in the t_open(3NSL) flags, no data will be sent to the remote user.
If a user does not wish to send data and reason code to the remote user, the value of discon may be a null pointer.
This function is an optional service of the transport provider, only supported by providers of service type T_COTS_ORD. The flag T_ORDRELDATA in the info→flag field returned by t_open(3NSL) or t_getinfo(3NSL) indicates that the provider supports orderly release user data.
This function may not be available on all systems.
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and t_errno is set to indicate an error.
On failure, t_errno is set to one of the following:
In the TLI interface definition, no counterpart of this routine was defined.

The interfaces t_sndreldata() and t_rcvreldata(3NSL) are only for use with a specific transport called "minimal OSI," which is not available on the Solaris platform. These interfaces are not available for use in conjunction with Internet Transports (TCP or UDP).
