變量16進制顯示VSCode display hex values for variables in debug mode

 

VS CODE 查看內存

 

MemoryView - Visual Studio Marketplace

 

第一步：Add new memory view... 

第二步：輸入變量地址  &array

第三步：需要手動刷新內存

 

 

1、在程序中增加dump函數，如下

2、VScode的監視（WATCH）窗口，是可以調用函數的, 在監視窗口 Add Expression,  

memory_dump(argv, 32)      memory_dump(0x7fffffffdb58, 32)

void memory_dump(void *ptr, int len)
{
    int i;
    for (i = 0; i < len; i+=4) {
        if (i % 16 == 0 && i != 0)
            printf(" ");
        if (i % 64 == 0 && i != 0)
            printf("\n");
        printf("%08x ", *((uint32_t *)(ptr + i)));
    }
    printf("\n");
}

 其他方法

在“調試控制台 debug console”下用命令 “-exec x/8x argv "可以查看數組內容，那么在監視(watch)窗口下也可以添加"-exec x/8x argv", 調試的時候隨着單步F10，可以自動執行這個命令（不需要再調試控制台窗口手動執行命令）

Suffixes used in VSCode's Watch pane:

var, h

var, d

var, b

var, o

 

 

From the (GDB) Debug Console use -exec set output-radix 16 for hex, set it to 10 for decimal.

 

his answer applies to GDB debugging.

For an active debug session, type the following in the debug console:

-exec set output-radix 16

 

To apply this every time the debugger runs, add text "set output-radix 16" in the "setupCommands" section of launch.json

"setupCommands": [
    {
        "description": "Enable pretty-printing for gdb",
        "text": "-enable-pretty-printing",
        "ignoreFailures": true
    },
    { "text": "set output-radix 16" }
]
