timod(7) Miscellaneous Information Manual timod(7) NAME
timod - STREAMS module for converting ioctl() calls into TI messages DESCRIPTION
The timod module is a STREAMS module that converts ioctl() calls from a transport user supporting the Transport Interface (TI) into mes- sages that a transport protocol provider supporting TI can consume. This allows the user to initiate TI functions as atomic operations. The user places and removes the timod module on a device stream by calling the STREAMS I_PUSH ioctl() and I_POP ioctl() functions. The timod module recognizes and processes STREAMS messages generated by I_STR ioctl() calls containing the following TI commands: This TI command binds an address to the transport protocol provider. The STREAMS message that the module issues to the TI_BIND ioctl() call is equivalent to the TI message type T_BIND_REQ. The STREAMS message that the module returns in response to the successful completion of the TI_BIND ioctl() call is equivalent to the TI message type TI_BIND_ACK. This TI command unbinds an address from the transport protocol provider. The STREAMS message that the module issues to the TI_UNBIND ioctl() call is equivalent to the TI message type T_UNBIND_REQ. The STREAMS message that the module returns in response to the successful completion of the TI_UNBIND ioctl() call is equivalent to the TI mes- sage type TI_OK_ACK. This TI command gets the TI protocol-specific information from the transport protocol provider. The STREAMS message that the module issues to the TI_GETINFO ioctl() call is equivalent to the TI message type T_INFO_REQ. The STREAMS message that the module returns in response to the successful completion of the TI_GETINFO ioctl() call is equivalent to the TI message type TI_INFO_ACK. This TI command gets, sets, or negotiates TI protocol-specific options with the transport protocol provider. The STREAMS message that the module issues to the TI_OPTMGMT ioctl() call is equivalent to the TI message type T_OPTMGMT_REQ. The STREAMS message that the module returns in response to the successful completion of the TI_OPTMGMT ioctl() call is equivalent to the TI message type TI_OPTMGMT_ACK. The timod module transparently passes any STREAMS messages that are not generated by the ioctl() calls previously described to the neigh- boring module or driver. RETURN VALUES If the timod module returns an error for an ioctl() call, the lower 8 bits of the return value will be one of the TI error codes defined in the sys/tiusr.h header file. If the TI error is of the type TSYERR, then the second 8 bits of the return value will contain an error as defined in the sys/errno.h header file. FILES
