int t_sndrel(int fildes);
MT-Safe
This function 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. fildes identifies the local transport endpoint
where the connection exists. After issuing t_sndrel(), 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.
This
function is an optional service of the transport provider, and is only
supported if the transport provider returned service type T_COTS_ORD
on
t_open() or t_getinfo().
If t_sndrel() is issued from an invalid state,
the provider will generate an EPROTO
protocol error; however, this error
may not occur until a subsequent reference to the transport endpoint.
t_sndrel() returns 0 on success. On failure t_sndrel() returns -1,
t_errno is set to indicate the error, and possibly errno is set.
TSYSERR
A system error has occurred during execution of this function, errno will
be set to the specific error.
On failure, t_errno will be set to
one of the following:
- TBADF
- The specified file descriptor does not refer
to a transport endpoint.
- TFLOW
- O_NDELAY
or O_NONBLOCK
was set, but the
flow control mechanism prevented the transport provider from accepting
the function at this time.
- TNOTSUPPORT
- This function is not supported by
the underlying transport provider.
