Returns a structure defined in the /usr/include/sys/devinfo.h file.
The IOCINFO ioctl operation returns a structure that is defined in the /usr/include/sys/devinfo.h header file. The caller supplies the address to an area that is of the type struct devinfo . This area is in the arg parameter to the IOCINFO operation. The device-type field for this component is DD_BUS; the subtype is DS_SDA.
The IOCINFO operation is defined for all device drivers that use the ioctl subroutine, as follows:
The operation returns a devinfo structure. The caller supplies the address of this structure in the argument to the IOCINFO operation. The device type in this structure is DD_BUS, and the subtype is DS_SDA. The flags field is set to DF_FIXED.
