[英]Setting multiple line values to a variable in GDB
我有一个char数组x
,我需要给它一个跨多行的输入。
GDB接受x:="value"
类的输入,但是如何使它接受诸如x:="value"
x := "this is a multiple lines
input. We are now in second line"
这里的问题不是让GDB识别\\ n而是当我输入很长的字符串输入时使我的脚本可读。
例如:代替x =“这是一个非常长的文本输入。非常长的输入。非常长的输入”我需要给x =“这是一个非常长的文本输入。非常长的输入。非常长的输入”
我希望嵌入式换行符可以正常工作:
gdb$ set var x = "this is a long\nstring with\nmultiple lines\in it!"
但是我现在无法访问gdb进行尝试。
用反斜杠结束该行,然后继续下一行。
$ gdb s
(gdb) list
1 #include <stdio.h>
2
3 char buf[512];
4
5 main()
6 {
7 printf("%s\n", buf);
8 }
(gdb) break main
Breakpoint 1 at 0x80483bd: file s.c, line 7.
(gdb) run
Starting program: s
Breakpoint 1, main () at s.c:7
7 printf("%s\n", buf);
(gdb) set buf="I have always wished for my computer to be as easy to use \
as my telephone; my wish has come true because I can no longer figure out \
how to use my telephone. --Bjarne Stroustrup."
(gdb) cont
Continuing.
I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone. --Bjarne Stroustrup.
Program exited with code 0262.
