t_unbind - Disables a transport endpoint.


XTI Library (libxti.a)


#include <xti.h> int t_unbind( int fd) ;


Interfaces documented on this reference page conform to industry standards as follows: t_unbind: XPG4-UNIX Refer to the standards(5) reference page for more information about industry standards and associated tags.


The following table summarizes the relevance of input parameter data before and after t_bind() is called: Parameter Before Call After Call ____________________________________ fd y n Notes to Table: y This is a meaningful parameter. n This is not a meaningful parameter. fd Specifies a file descriptor returned by the t_open() function that identifies an active, previously bound local transport endpoint.


The t_bind() function can be called only in the T_IDLE transport provider state.


The t_unbind() XTI service function is used in connection-oriented and connectionless modes to disable the transport endpoint, specified by the file descriptor that was previously bound by a t_bind() call. When t_bind() completes, no further data destined for this transport endpoint or events are accepted by the transport provider. An endpoint that has been disabled using t_unbind() can be enabled by a subsequent call to t_bind().


Upon successful completion, a value of 0 (zero) is returned. Otherwise, a value of -1 is returned and t_errno is set to indicate the error.


If the t_unbind() function fails, t_errno is set to one of the following values: [TBADF] File descriptor fd is not a valid transport endpoint. [TOUTSTATE] This function was issued in the wrong sequence. [TLOOK] An asynchronous event occurred at the transport endpoint specified by the fd parameter. [TSYSERR] A system error occurred during execution of this function. [TPROTO] This error indicates that a communication problem has been detected between XTI and the transport provider for which there is no other suitable XTI(t_errno).
