C++ convert function to unsigned char array - eyehollow - Oct 19, 2018

How to convert function to unsigned char array (*void pointer)
I'm sorry if I do not understand correctly what is *void pointer
For example i have functions like this

Example 1

Code 
void test(){

  std::cout << "Hello" << std::endl;

}

Example 2

Code 
void test2(int a){

  std::cout << "Hello" << std::endl;

  std::cout << std::to_string(a) << std::endl;

}

Example 3

Code 
int test3(int a){

  return a;

}

In short i need univesal method to convert any method(function) to raw data.
I need to save this functions as array or vector of unsigned char.

Someone can help me?
Thank you so much.

Code 
unsigned char* function = (unsigned char*)test;

//remove page protection

unsigned char functioncopy[SIZE_OF_FUNCTION] = {0};

memcpy(functioncopy,function,SIZE_OF_FUNCTION);

//restore page protection
