t_sndrel() - initiate an orderly release SYNOPSIS
DESCRIPTION
The function is used in connection-oriented mode to initiate an orderly release at a transport endpoint specified by fd, which is a file descriptor previously returned by the function. After this orderly release is indicated, the transport user should not try to send more data through that transport endpoint. An attempt to send more data to a released transport endpoint may block continuously. However, the transport user may continue to receive data over the connection until an orderly release indication is received. This function is an optional service of the transport provider and is only supported if the transport provider returned service type on or Note HP OSI XTI does not support Fork Safety is not fork-safe. RETURN VALUE

[TFLOW] Asynchronous mode is indicated because was set, but the transport provider cannot accept a release because of flow-con- trol restrictions. [TLOOK] An asynchronous event has occurred on this transport endpoint and requires immediate attention. [TNOTSUPPORT] This function is not supported by the underlying transport provider. [TSYSERR] A system error has occurred during execution of this function. [TPROTO] (XTI only) This error indicates that a communication problem has been detected between XTI and the transport provider for which there is no other suitable XTI ( SEE ALSO
