int tokioctl (devno, cmd, arg, devflag, chan, ext) dev_t devno; int cmd, arg; ulong devflag; int chan, ext;
| devno | Specifies major and minor device numbers. |
| cmd | Specifies the operation to be performed. The possible tokioctl operation codes can be found in the /usr/include/sys/ioctl.h, /usr/include/sys/comio.h, and /usr/include/sys/tokuser.h files. |
| arg | Specifies the address of the tokioctl parameter block. |
| devflag | Indicates the conditions under which the device was opened. |
| chan | Specifies the channel number assigned by the tokmpx entry point. |
| ext | This parameter is not used by the token-ring device handler. |
The tokioctl entry point provides various functions for controlling the token-ring device handler. The possible tokioctl operations are:
| Operation | Description |
|---|---|
| CIO_GET_FASTWRT | Gets function address for the tokfastwrt operation. |
| CIO_GET_STAT | Gets device status. |
| CIO_HALT | Halts the device. |
| CIO_QUERY | Queries device statistics. |
| CIO_START | Starts the device. |
| IOCINFO | I/O character information. |
| TOK_FUNC_ADDR | Sets functional addresses. |
| TOK_GRP_ADDR | Sets the group address. |
| TOK_QVPD | Queries vital product data (VPD). |
| TOK_RING_INFO | Queries token-ring information. |
The tokioctl entry point functions with a Token-Ring High-Performance Network Adapter that has been correctly configured for use on a qualified network. Consult adapter specifications for more information on configuring the adapter and network qualifications.
The tokioctl entry point can be called from the process environment only.
The tokmpx entry point.
