The hooking function:
void WriteJMP(byte* location, byte* newFunction){
DWORD dwOldProtection;
VirtualProtect(location, 5, PAGE_EXECUTE_READWRITE, &dwOldProtection);
location[0] = 0xE9;
*((dword*)(location + 1)) = (dword)(newFunction - location) - 5;
VirtualProtect(location, 5, dwOldProtection, &dwOldProtection);
}
DWORD dwOldProtection;
VirtualProtect(location, 5, PAGE_EXECUTE_READWRITE, &dwOldProtection);
location[0] = 0xE9;
*((dword*)(location + 1)) = (dword)(newFunction - location) - 5;
VirtualProtect(location, 5, dwOldProtection, &dwOldProtection);
}
