如何初始化无符号字符数组？

Question

我真正想要实现的是一个动态字节模式数组，当我缓冲二进制文件时，我可以将其用作模式搜索器。但我现在开始基本。我有以下代码，我基于 StackOverflow 上的一个示例。

How to Initialize a Multidimensional Char Array in C?

typedef unsigned char BYTE;

int main()
{
    BYTE *p[2][4] = {
        {0x44,0x58,0x54,0x31},
        {0x44,0x58,0x54,0x00}
    };

    return 0;
}

我用 mingw32 for Windows 编译它。

D:\> gcc example.c -o example.exe

我在尝试编译时收到以下警告。

example.c: In function 'main':
example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default]
example.c:6:3: warning: (near initialization for 'p[0][0]') [enabled by default]
example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default]
example.c:6:3: warning: (near initialization for 'p[0][1]') [enabled by default]

example.c:7:3: warning: initialization makes pointer from integer without a cast [enabled by default]
example.c:7:3: warning: (near initialization for 'p[1][2]') [enabled by default]

我不明白这个警告的性质。我该如何解决它？谢谢。

从BYTE *p[2][4] 中删除*：

BYTE p[2][4] = {
    {0x44,0x58,0x54,0x31},
    {0x44,0x58,0x54,0x00}
};

您需要char 的多维数组：BYTE p[2][4] 而不是pointer-to-char 的多维数组。
