Re: few questions about the system call in a small C program
This is entirely platform dependant.
C library functions could call multiple system calls, it depends on the implementation.
Most Unix systems have methods of tracing process execution, there is ktrace(1) on BSD/Mac, DTrace.. and no doubt 15 or so separate Linux projects that can do the same.
This has little to do with the topic of OSDev, as for this being homework, there is a reason I didn't have kids.
