What is the difference between the execlp and execvp system calls?

Question

Question

engineering Computer-Science

Answer 1

Answer #1

In the execlp we give command line arguments individually to the function.
In the execvp command line arguments are passed to the functions as an array of pointers.
Syntax for execlp: int execlp(char const *file, char const *arg0, ...);
Syntax for execvp: int execvp(char const *file, char const *argv[]);
In the execvp argument are in vector and in execlp arguments are in a list.

Purpose: to understand mode switch penalty and the cost difference among system calls. Your task is to write a C program that measures the latencies of various system calls. In particular, you want to know 1) the cost of CPU mode switch by measuring a light-weight system call which does very little thing in the kernel, and 2) the cost of heavier system calls which triggers a lot of activities inside the kernel. Your program should measure the latencies of...
