1.gdb下调试多进程程序只需要以下几条命令即可
        
    除此之外还可以查看正在调试的进程 info inferiors, 同时也可以将当前正在调试的进程切换到另外一个进程中让其取运行
    2.代码调试演示

#include<stdio.h>
#include<stdlib.h>
#include<unistd.h>void father_process();
void child_process();int main()
{pid_t pid = fork();if (pid < 0){fprintf(stderr, "fork failure\n");exit(-1);}else if (pid > 0){father_process();}else{child_process();}return 0;
}void father_process()
{pid_t pid = getpid();printf("father pid = %d\n", pid);printf("hello world\n");
}void child_process()
{pid_t pid = getpid();printf("child pid = %d\n", pid);
}
