Provides various functions for controlling the Serial Optical Link (SOL) device handler.
#include <sys/device.h> #include <sys/devinfo.h> #include <sys/ioctl.h> #include <sys/comio.h> #include <sys/soluser.h> int sol_ioctl (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 sol_ioctl operation codes are in the /usr/include/sys/ioctl.h, /usr/include/sys/comio.h, and /usr/include/sys/soluser.h files. |
| arg | Specifies the address of the sol_ioctl parameter block. |
| devflag | Indicates the conditions under which the device was opened. |
| chan | Specifies the channel number assigned by the sol_mpx entry point. |
| ext | This parameter is not used by the SOL device handler. |
The sol_ioctl entry point provides various functions for controlling the SOL device handler. The possible sol_ioctl operations are:
| CIO_GET_FASTWRT | Provides the attributes of the sol_fastwrt entry point. |
| CIO_GET_STAT | Gets device status. |
| CIO_HALT | Halts the device. |
| CIO_QUERY | Queries device statistics. |
| CIO_START | Starts the device. |
| IOCINFO | Returns I/O character information. |
| SOL_CHECK_PRID | Checks whether a processor ID is connected. |
| SOL_GET_PRIDS | Gets connected processor IDs. |
The sol_ioctl entry point can be called from the process environment only.
The sol_ioctl entry point functions with a Serial Link Adapter and Serial Optical Channel Converter that have been correctly configured for use on a qualified network. Consult hardware specifications for more information on configuring hardware and network qualifications.
