It long ago ceased to be neces‐ sary, and it will cause problems with modern versions of the C library. 3/29/2018; 2 minutes to read In this article. Re ifconfig vs ip: What’s Difference and Comparing Network Configuration of netlink socket mechanism for the same which is a much more flexible successor of ioctl Device IO vs Device Driver Leverages netlink and other control channels Kernel driver IOCTL or CPU innovation required >> What settings should be implemented as socket option vs. Creating a bridge IOCTL_MOUNTDEV_LINK_CREATED IOCTL. Netlink sockets and messages are extensively used on Linux to exchange information between userspace and kernel. Should have good understanding of NetLink sockets communication between Linux Kernel space and user space. net › 论坛 › 程序设计 › 内核源码 › 用户空间内核空间ipc总结(sockopt,ioctl,mmap,netlink,p 高级模式 B Color Image Link Quote Code Smilies ioctl vs netlink vs memmap to communicate between kernel space and user space: Programming Languages: Got some statistics information of our custom hardware to be displayed whenever user asks for using a command in the Linux user space. It was supposed to be an opportunity for NetLink NBN Trust to make a statement about its investment merits to Singapore investors. The rawmidi also allows to obtaining the information via ioctl of ctl API. Unfortunately, the Linux kernel underwent a name change and I can't figure out which /dev location is the right one. h if_link. 780 per unit. word size I able to connect to a 802. One of the main highlight which separates it from its ancient counterpart ifconfig is that latter uses ioctl for network configuration, which is a less appreciated way of interaction with kernel while former takes advantage of netlink socket mechanism for the same which is a much more flexible successor of ioctl for inter-communication between [go-nuts] cgo vs ioctl system calls; Tim K. netlink vs ioctl
