    NAME

    timod - Transport Interface cooperating STREAMS module
     
    

    SYNOPSIS

    #include <sys/stropts.h> 
    

    ioctl(fildes, I_STR, &my_strioctl);
    

     

    DESCRIPTION

    timod is a STREAMS module for use with the Transport Interface ("TI") functions of the Network Services library. The timod module converts a set of ioctl(2) calls into STREAMS messages that may be consumed by a transport protocol provider that supports the Transport Interface. This allows a user to initiate certain TI functions as atomic operations.

    The timod module must be pushed onto only a stream terminated by a transport protocol provider that supports the TI.

    All STREAMS messages, with the exception of the message types generated from the ioctl commands described below, will be transparently passed to the neighboring module or driver. The messages generated from the following ioctl commands are recognized and processed by the timod module. The format of the ioctl call is:

    #include <sys/stropts.h>
                    -
                    -
    struct strioctl my_strioctl;
                    -
                    -
    strioctl.ic_cmd = cmd;
    strioctl.ic_timout = INFTIM;
    strioctl.ic_len = size;
    strioctl.ic_dp = (char *)buf
    ioctl(fildes, I_STR, &my_strioctl);
    

    On issuance, size is the size of the appropriate TI message to be sent to the transport provider and on return size is the size of the appropriate TI message from the transport provider in response to the issued TI message. buf is a pointer to a buffer large enough to hold the contents of the appropriate TI messages. The TI message types are defined in <sys/tihdr.h>. The possible values for the cmd field are:

    TI_BIND

    Bind an address to the underlying transport protocol provider. The message issued to the TI_BIND ioctl is equivalent to the TI message type T_BIND_REQ and the message returned by the successful completion of the ioctl is equivalent to the TI message type T_BIND_ACK.

    TI_UNBIND

    Unbind an address from the underlying transport protocol provider. The message issued to the TI_UNBIND ioctl is equivalent to the TI message type T_UNBIND_REQ and the message returned by the successful completion of the ioctl is equivalent to the TI message type T_OK_ACK.

    TI_GETINFO

    Get the TI protocol specific information from the transport protocol provider. The message issued to the TI_GETINFO ioctl is equivalent to the TI message type T_INFO_REQ and the message returned by the successful completion of the ioctl is equivalent to the TI message type T_INFO_ACK.

    TI_OPTMGMT

    Get, set, or negotiate protocol specific options with the transport protocol provider. The message issued to the TI_OPTMGMT ioctl is equivalent to the TI message type T_OPTMGMT_REQ and the message returned by the successful completion of the ioctl is equivalent to the TI message type T_OPTMGMT_ACK.

    DIAGNOSTICS

    If the ioctl returns with a value greater than 0, the lower 8 bits of the return value will be one of the TI error codes as defined in <sys/tiuser.h>. If the TI error is of type TSYSERR, then the next 8 bits of the return value will contain an error as defined in <sys/errno.h> (see Intro(3)).
