Answer:
Yes, it is important for a programmer to know which library procedures result in system calls. A system call is a request made by an application to the operating system kernel for performing tasks such as input/output operations, process management, memory management, and more. When a programmer knows which library procedures result in system calls, they can optimize their code and improve its performance by reducing the number of system calls made by their program1 This can be especially important when writing high-performance applications that require low latency and high throughput.
Knowing which library procedures result in system calls can also help programmers write more secure code by avoiding potential security vulnerabilities. For example, if a programmer knows that a particular library procedure makes a system call that can be exploited by attackers, they can take steps to mitigate this risk by either avoiding the use of that procedure or by implementing additional security measures.
In summary, knowing which library procedures result in system calls can help programmers optimize their code for performance and improve its security by avoiding potential vulnerabilities.
