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
Defines the error codes for TI functions. Defines the message types for TI. Defines the error codes for system errors.
