Question

Which of the following is responsible for coordinating the system call within an application and the WIN32 subsystem?

(a) kernel

(b) file system

(c) LPC

(d) network support

This question was posed to me in an interview for job.

I'd like to ask this question from Characteristics of Windows NT-II in section Real Time Operating systems of Embedded Systems

Answer 1

Correct option is (c) LPC

Easy explanation: The local procedure call is responsible for coordinating the system calls from the WIN32 subsystem and an application. Depending upon the type of the system call, the application will be routed directly with the LPC without going through the WIN32 subsystem.
