Hi,

I want to invoke getpid() system call using syscall. Here's the code snippet below. But, I can't find anything in dmesg|tail output.

#include <sys/types.h>

int main() { pid_tret = syscall(20); return 0; }

Have you seen the code of the system call sys_getpid ? I dont find anything there which will print in dmesg .. ofcourse you can modify the code and then you will get the output in dmesg .
