void arrange_message(unsigned char*,unsigned char data_order);

arrange_message(THREE,1);

void arrange_message(unsigned char data_wrtn[],unsigned char data_order)

}
}

finally it work ok

I´m still curious about this implementation :

void arrange_message(unsigned char*,unsigned char data_order);

There is not missing the 1rst input variable ?

I don't understand, why wasn't it working the first time and it woks now?

I have no idea how this works because I have never used this way.

What I usually do is

void my_function (char *myarray_p)

   some_other_variable = *myarray_p++; // assign the value pointed by p, and then increment the address p
 
//or it can also be done with a loop.
}
 
//To call the function I send the address of the array
my_function(myarray);

like you i don't know why it isn't work first and work last
i think that first i write that temp1[p]= & data_wrtn[p]; and i do understand why we use the * pointer and what is the meaning of use it with array
i understand that we use use pointer to point to the first parameter in array
