t_unbind(3)
NAME
  t_unbind - Disables a transport endpoint.

LIBRARY
  XTI Library (libxti.a)

SYNOPSIS
  #include <xti.h>

  int t_unbind(
    int fd) ;

STANDARDS
  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.

PARAMETERS
  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.

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

DESCRIPTION
  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().




RETURN VALUES
  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.

ERRORS
  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).
