Thread: [Help] Reading Pointer

recently i was learning to make dll for injection and i found this func code:

Code:

unsigned long ReadPointer(unsigned long ulBase, int iOffset)
{
   __try { return *(unsigned long*)(*(unsigned long*)ulBase + iOffset); }
   __except (EXCEPTION_EXECUTE_HANDLER) { return 0; }
}

for example :
addr = 0x0012345
off = 0x10

readpointer(addr, off) -> let say this read value (DWORD) = 1701277249 and char/string value = egnA

DWORD/unsigned long is 4 byte which mean can contain up to 4 char.

i wanna ask how to get value into char/string which have control size that could contain up to 24 char.

ps : im newbie c++

moderator can close this now..

here some solution i got..

Code:

LPCSTR ReadStringPointer(unsigned long ulBase, int iOffset)
{
__try { return (LPCSTR)(*(unsigned long*)ulBase + iOffset); }
__except (EXCEPTION_EXECUTE_HANDLER) { return "-"; }
}

and this..

Code:

std::string my_string((char*)0xdeadbeef, 24);
