How to create a device in /dev automatically upon loading of the kernel module for a device driver?

Question

I am attempting to develop Linux device drivers and as my first attempt I am trying to develop a char device driver that has the following file options,

st         


        

Answer 1

I could see entries within /dev after creating node by running following command at console.

sudo mknod -m 0666 /dev/msio c 22 0

The user was not root, so I had to use sudo. My entry name was msio, a character device with major and minor number 22, 0 respectively.

I will let you know if this can be achieved programatically.
