hello there, I am working on 2.4 kernel. I want to create some character devices during insmod and remove the devices at the time of rmmod. I used the following lines in LKM : dev_t dev; dev = (major<< 8)|(0); sys_mknod(DEVICE_NAME,S_IFCHR|S_IRWXU,dev); used the .h file, "/lib/modules/`uname -r`/build/include/linux/syscalls.h" I confronted with a warning as "implicit declaration of function sys_mknod", though I included the necessary header file. Can any one suggest how to resolve the problem. Thanks in advance. - kishore, packetware. -- Kernelnewbies: Help each other learn about the Linux kernel.
