Hi all,
I am trying to develop a VxBus driver. But i am not able to understand how ioctl calls are handeled here.
How ioctl calls can be registered with the I/O framework?
Can someone help me to understand this?

and below can be helpful
blkDevInitStruct.bd_blkRd = (FUNCPTR)myBlockRead; //FUNCPTR. function to read blocks
blkDevInitStruct.bd_blkWrt = (FUNCPTR)myBlkDevWrt; //FUNCPTR. function to write blocks
blkDevInitStruct.bd_ioctl = (FUNCPTR)myBlkDevIoctl; //FUNCPTR. function to ioctl device
blkDevInitStruct.bd_reset = (FUNCPTR)myBlkDevReset; //FUNCPTR. function to reset device
blkDevInitStruct.bd_statusChk = (FUNCPTR)myBlkDevStatus; //FUNCPTR. function to check status
