    NAME

    t_getstate - get the current state
     
    

    SYNOPSIS

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

     

    DESCRIPTION

    This routine is part of the XTI interfaces which evolved from the TLI interfaces. XTI represents the future evolution of these interfaces. 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.

    The t_getstate() function returns the current state of the provider associated with the transport endpoint specified by fd.  

    RETURN VALUES

    State is returned upon successful completion. Otherwise, a value of -1 is returned and t_errno is set to indicate an error. The current state is one of the following:

    T_UNBND

    Unbound.

    T_IDLE

    Idle.

    T_OUTCON

    Outgoing connection pending.

    T_INCON

    Incoming connection pending.

    T_DATAXFER

    Data transfer.

    T_OUTREL

    Outgoing direction orderly release sent.

    T_INREL

    Incoming direction orderly release received.

    If the provider is undergoing a state transition when t_getstate() is called, the function will fail.  

    ERRORS

    On failure, t_errno is set to one of the following:

    TBADF

    The specified file descriptor does not refer to a transport endpoint.

    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).

    TSTATECHNG

    The transport provider is undergoing a transient state change.

    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. They should use the header:

    #include <tiuser.h> 
    

     

    Error Description Values

    The t_errno value that can be set by the XTI interface and cannot be set by the TLI interface is:

    TPROTO  

    ATTRIBUTES

    See attributes(5) for descriptions of the following attributes:
