[Dev-C++] function errors

[Noorez K. <coo...@ho...>]

#include <iostream>
#include <conio.h>
using namespace std;

namespace myf
{
    void wait(char message[], char contin)
    {
        if(contin == '') //make sure that contin is not blank
        {
            //if it is...
            cout << "Press any key to continue...";
            while( !kbhit() )
            {
            }
            return;
        }
        cout << message << endl; //do what is told
        char get;
        while(1) //loop till we get the correct value
        {
            get = getch(); //'empty character constant' error
            if(get == contin)
            {
                return;
            }
        }
    }//end wait()
}//namespace myf


I am trying to put this function into a library of other functions of my own 
but I'm getting a compile error on the marked line.
