NAME
t_errno - XTI error return value SYNOPSIS
#include <xti.h> DESCRIPTION
This error return value is part of the XTI interfaces that evolved from the TLI interfaces. XTI represents the future evolution of these interfaces. However, TLI interfaces are supported for compatibility. When using a TLI interface that has the same name as an XTI inter- faces, a different headerfile, <tiuser.h>, must be used. Refer the the TLI COMPATIBILITY section for a description of differences between the two interfaces. t_errno is used by XTI functions to return error values. XTI functions provide an error number in t_errno which has type int and is defined in <xti.h>. The value of t_errno will be defined only after a call to a XTI function for which it is explicitly stated to be set and until it is changed by the next XTI function call. The value of t_errno should only be examined when it is indicated to be valid by a function's return value. Programs should obtain the defini- tion of t_errno by the inclusion of <xti.h>. The practice of defining t_errno in program as extern int t_errno is obsolescent. No XTI function sets t_errno to 0 to indicate an error. It is unspecified whether t_errno is a macro or an identifier with external linkage. It represents a modifiable lvalue of type int. If a macro definition is suppressed in order to access an actual object or a program defines an identifier with name t_errno, the behavior is undefined. The symbolic values stored in t_errno by an XTI function are defined in the ERRORS sections in all relevant XTI function definition pages. TLI COMPATIBILITY
t_errno is also used by TLI functions to return error values. The XTI and TLI interface definitions have common names but use different header files. This, and other semantic differences between the two interfaces are described in the subsections below. Interface Header The XTI interfaces use the header file, <xti.h>. TLI interfaces should not use this header. They should use the header: #include <tiuser.h> Error Description Values The t_errno values that can be set by the XTI interface but cannot be set by the TLI interface are: TNOSTRUCTYPE TBADNAME TBADQLEN TADDRBUSY TINDOUT TPROVMISMATCH TRESADDR TQFULL TPROTO ATTRIBUTES

t_unbind(3NSL)					       Networking Services Library Functions					    t_unbind(3NSL)

NAME
t_unbind - disable a transport endpoint SYNOPSIS
#include <xti.h> int t_unbind(int fd); DESCRIPTION
The This routine is part of the XTI interfaces which evolved from the TLI interfaces. XTI represents the future evolution of these inter- faces. However, TLI interfaces are supported for compatibility. When using a TLI routine that has the same name as an XTI routine, the tiuser.h header file must be used. Refer to the TLI COMPATIBILITY section for a description of differences between the two interfaces. t_unbind() function disables the transport endpoint specified by fd which was previously bound by t_bind(3NSL). On completion of this call, no further data or events destined for this transport endpoint will be accepted by the transport provider. An endpoint which is disabled by using t_unbind() can be enabled by a subsequent call to t_bind(3NSL). RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and t_errno is set to indicate an error. VALID STATES
T_IDLE. ERRORS
On failure, t_errno is set to one of the following: TBADF The specified file descriptor does not refer to a transport endpoint. TLOOK An asynchronous event has occurred on this transport endpoint. TOUTSTATE The communications endpoint referenced by fd is not in one of the states in which a call to this function is valid. 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 error (t_errno). TSYSERR A system error has occurred during execution of this function. TLI COMPATIBILITY
The XTI and TLI interface definitions have common names but use different header files. This, and other semantic differences between the two interfaces are described in the subsections below. Interface Header The XTI interfaces use the header file, xti.h . TLI interfaces should not use this header.
