I understand how to use get_param, but what I'm curious about is how useful get_param_byref is. I played around with it thinking that if I did something like...

PHP Code:

            new i = get_param_byref(3);
            i++; 


Thinking that the parameter entered would change. It didn't. So can anyone tell me the purpose of this with a usage? (Yes, I know that you can do set_param_byref to change the by reference value.)

It does the same thing in Pawn, so you don't see a difference.
The module is written differently, but the byref function makes no sense to even exist.

//get a byvalue parameter
//get_param(num)
static cell AMX_NATIVE_CALL get_param(AMX *amx, cell *params)
{
	if (!g_pCurNative || (g_pCurNative->amx != amx))
	{
		LogError(amx, AMX_ERR_NATIVE, "Not currently in a dynamic native");
		return 0;
	}
	if (g_pCurNative->style)
	{
		LogError(amx, AMX_ERR_NATIVE, "Wrong style of dynamic native");
		return 0;
	}
	//get parameter index to read from
	int p = params[1];

	//return value from the stored params in the function (new memory space)
	return g_Params[p];
}

//get_param_byref(num)
static cell AMX_NATIVE_CALL get_param_byref(AMX *amx, cell *params)
{
	if (!g_pCurNative || (g_pCurNative->amx != amx))
	{
		LogError(amx, AMX_ERR_NATIVE, "Not currently in a dynamic native");
		return 0;
	}
	if (g_pCurNative->style)
	{
		LogError(amx, AMX_ERR_NATIVE, "Wrong style of dynamic native");
		return 0;
	}
	//get parameter index to read from
	int p = params[1];

	//get the memory address of the variable
	cell *addr = get_amxaddr(g_pCaller, g_Params[p]);

	//return the value from the memory address
	return addr[0];
}
