i have a char buffer[100]
and i'm trying to use gdb to read the contents out of it at various stages of runtime.
i use p buffer
and i get
"/*\000\000\000\000\000\000????X?o\000\025\202\004\b", '\0' <repeats 12 times>, ".N=?", '\0' <repeats 24 times>, "`\203\004\b\000\000\000\000L\227\004\bX????\202\004\b?\017\204\000\f?\203\000\210???i\205\004\b??r"
how do i get p
to convert it into a readable format???
x/s buffer
应该将数组的内容显示为空终止字符串(这是我假设你喜欢的)。
If you want to get rid of the junk after the terminating null (so you'll just see "/*"
for this string) you can use:
p (char*)buffer
At the moment gdb
is printing your variable as an array, so it's showing all 100 characters; casting it to char*
makes it print it as a C string.
