Trying to make system call results in no action

I am trying to communicate with the kernel through the /proc filesystem. I have written abc to my def module. But on doing cat cat /proc/def, I am not able to see "abc". Here is my code:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main (int argc,char **argv)
{
char mystr[1000];
char str1[]="abc";
sprintf(mystr, "echo \"%s\" > /proc/fortune\n", str1 );
system("mystr");
}
