Question

我已经知道如何通过运行以下命令在GDB模式下传递参数：＆＃34;运行参数＆＃34;。但是，当继续使用n或s进行调试时，我想将数据传递给我的程序，比方说文本/字符串。例如，我想发送一个字符串作为＆＃34;测试＆＃34;到我的程序，因为我的程序总是等待从控制台接收命令。如果我输入＆＃34;测试＆＃34;它会说＆＃34;未定义的命令：＆＃34;测试＆＃34;。尝试帮助＆＃34;。

(gdb) b 100
(gdb) run "pass parameters to program here"
(gdb) n 
(gdb) Now I want to send a string to my program, how can I do it?

那么在步骤模式下调试GDB时，如何将此文本发送到我的程序呢？非常感谢。

如果是真的，只需输入。示例会话：

5       fgets(buffer, 100, stdin);
(gdb) n
Hello, world!
6       printf("You entered: %s", buffer);
(gdb) n
You entered: Hello, world!
7       return 0;
(gdb) continue
Continuing.

第一个Hello, world!之后的n只是正常输入。

如何在GDB模式下传递输入数据进行编程C.已经传递参数并运行程序
