The process id of the running process can be obtained by using getpid() and that of its parent can be obtained by getppid() function. Here's the coding example:-

#include<unistd.h>

#include<stdio.h>

pid_t getpid(void)

pid_t getppid(void)

main()

{

printf("my pid=%d\n",getpid());

printf("parent's pid=%d\n",getppid());

return 0;

}
