What I am really trying to achieve is an array of dynamic byte patterns that I can use as a pattern searcher when I buffer binary files. But I am starting off basic for now. I have the following code that I based off of an example found on StackOverflow.
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;
}
I compile it with mingw32 for Windows.
D:\> gcc example.c -o example.exe
I get the following warnings when I try to compile.
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: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]
I don't understand the nature of this warning. How do I go about resolving it? Thanks.
Drop the *
from BYTE *p[2][4]
:
BYTE p[2][4] = {
{0x44,0x58,0x54,0x31},
{0x44,0x58,0x54,0x00}
};
You want a multidimensional array of char
: BYTE p[2][4]
not a multidimensional array of pointer-to-char
.
