Language in C Interview Questions and Answers
Question: Can we get the process identification number of the current program?
Answer: Yes! The macro getpid( ) gives us the process identification number of the program currently running. The process id. uniquely identifies a program. Under DOS, the getpid( ) returns the Program Segment Prefix as the process id. Following program illustrates the use of this macro.#include <stdio.h> #include <process.h> void main( ) { printf ( "The process identification number of this program is %Xn", getpid( ) ) ; } |
