NAME
       t_close - Closes a transport endpoint.

LIBRARY
       XTI Library (libxti.a)

SYNOPSIS
       #include <xti.h>

       int t _close( int fd) ;

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

PARAMETERS
       The following table summarizes the relevance of the input parameter before and after t_close() is called:

       Parameter   Before Call	 After Call
       -------------------------------------

	  fd		y	     n

       Notes  to table: This is a meaningful parameter.  This is not a meaningful parameter.  Specifies a file descriptor returned by the t_open()
       function that identifies a local transport endpoint.

VALID STATES
       The t_close() function is intended to be called in the T_UNBND transport provider state (see the DESCRIPTION section).

DESCRIPTION
       The t_close() XTI function is used in connection-oriented and connectionless transport service to inform  a  transport  provider  that  the
       transport  user	has  finished with the transport endpoint. The transport endpoint is specified by a file descriptor previously returned by
       the t_open() function. The t_close() function frees any local library resources associated with the transport endpoint  referenced  by  the
       file descriptor.

       The  t_close()  function  does  not  check  state information (see the t_getstate() function). Consequently, t_close() may be called in any
       transport provider state to close an open transport endpoint. When t_close() executes, local library resources associated with  the  trans-
       port  endpoint are automatically freed. In addition, a close() function is called for the referenced file descriptor.  The close() function
       aborts when there are no other file descriptors, in the current or any other process, that reference the  same  transport  endpoint.   When
       close() aborts, any connection that is associated with that transport endpoint is broken.

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_close()  function  fails, t_errno may be set to the following value: File descriptor fd does not refer to a valid transport end-
       point.  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).
