Initiates an orderly release of a transport connection.
Transport Layer Interface Library (libtli.a)
The t_sndrel subroutine is used to initiate an orderly release of a transport connection and indicates to the transport provider that the transport user has no more data to send.
After issuing a t_sndrel subroutine call, the user cannot send any more data over the connection. However, a user can continue to receive data if an orderly release indication has been received.
The t_sndrel subroutine is an optional service of the transport provider and is only supported if the transport provider returned service type T_COTS_ORD in the t_open or t_getinfo subroutine.
|fd||Identifies the local transport endpoint where the connection exists.|
On successful completion, the t_sndrel subroutine returns a value of 0. Otherwise, it returns a value of -1 and sets the t_errno variable to indicate the error.
If unsuccessful, the
t_errno variable is set to one of the following:
|TBADF||The specified file descriptor does not refer to a transport endpoint.|
|TFLOW||The O_NDELAY or O_NONBLOCK flag was set, but the flow-control mechanism prevented the transport provider from accepting the function at this time.|
|TLOOK||An asynchronous event has occurred on the transport end point reference by the fd parameter and requires immediate attention.|
|TNOTSUPPORT||This subroutine is not supported by the underlying transport provider.|
|TOUTSTATE||The subroutine was issued in the wrong sequence.|
|TSYSERR||A system error has occurred during execution of this subroutine.|
This subroutine is part of Base Operating System (BOS) Runtime.
