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.

What are you trying to see there? Why should any output come over there?

Do you need to use strace instead?

#include <sys/types.h>

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