1. Purpose of the experiment:
1. Linux: Refer to the textbook example, use the system call fork, create a new process, and execute
2. Java: use multi-thread library, create multi-thread, and execute
2. Experimental principle:
The parent process (thread) outputs the student ID and process ID (thread name),
Child process (thread) output name and process number (thread name)
3. Experimental environment: Vmware virtual machine and IDEA
4. Experimental steps:
#include<stdio.h>
void main(int argc,char *argv[])
{
int pid;
/*fork another process*/
pid =fork();
if(pid<0){ /*error process*/
printf("Fork Failed");
}
else if(pid==0){ /*child process*/
printf("jiangwang,process id is %d\n",getpid());
}
else{ /*parent process*/
/*parent will wait for the chile to complete*/
wait(NULL);
printf("2104423309,process id is %d\n",getpid());
}
}5. Experimental data recording and processing:
