Yes, this is the reason so that is why, want to perform one to many 
mapping between lib function and sys function.

Here is something which thought about output of the program as.


input : $ strace -xyz ./a.out
output:

in main():

	printf() -> 	syscall1();
		 	syscall2();
			syscall3();
			syscall4();
 
	fork() ->	syscall5();
			syscall6();
 			syscall7();

	<return value == 0>

in fun1():

	printf() ->     syscall8();
                        syscall9();
                        syscall10();
                        syscall11();
 
        fork() ->       syscall12();
                        syscall13();
                        syscall14();
	<return value == 56>

<normally program exited>


where syscall[i] represent the system call.
