    Problem in writing to a /sys file

    Hi,

    I am trying to change the frequency governor through a C program by writing to a file in /cpufreq folder. I change the permission by using command chmod but I am not able to write that file by using fprintf or fwrite functions.

    Can anyone please tell me a method to write to that file through a C program.

    Thank You.

    I suggest you do some googling on sys filesystem

    You can't just write to files in it
