Returns a structure that describes the Serial Optical Link (SOL) device.
The IOCINFO operation returns a structure that describes the SOL device. For this operation, the arg parameter points to the devinfo structure. This structure is defined in the /usr/include/sys/devinfo.h file and contains the following fields:
|devtype||Identifies the device type. The SOL device type is DD_NET_DH. This value is defined in the /usr/include/sys/devinfo.h file.|
|devsubtype||Identifies the device subtype. The SOL device subtype is DD_SOL. This value is defined in the /usr/include/sys/devinfo.h file.|
|broad_wrap||Specifies whether the wrapping of broadcast packets is supported by the device.|
|rdto||Specifies the configured receive data transfer offset (RDTO) value.|
|processor_id||Identifies the processor ID used by other systems to address this system. This is a customized attribute in the configuration database.|
The parameter block is filled in with the appropriate values upon return.
The IOCINFO operation can be called from the process environment only.
|EFAULT||Indicates the specified address is not valid.|
|EINVAL||Indicates the parameter is not valid.|
|ENODEV||Indicates the specified minor number is not valid.|
The IOCINFO operation 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.
