Why does this function always return 0?
<p>I have a function that is always returning 0.  The problem I believe is that data is an unsigned char, which is not part of the library. It needs to be unsigned char. So how can I make this work, because what I have doesn't.</p>

<pre><code>#include &lt;string&gt;
#include &lt;iostream&gt;

int Count( const std::string &amp; str, 
           const std::string &amp; obj ) {
    int a = 0;
    int b = 0;
    int c = 0;
    int d = 0;
    std::string ::size_type pos = 0;
    while( (pos = obj.find( str, pos )) 
                 != std::string::npos ) {
        a++;
        b++;
        c++;
        d++;
    pos += str.size();
    }
    return a;
    return b;
    return c;
    return d;
}
void printTcpContent(unsigned char *data,int)
{
    std::string s = (const char*) data;
    int a = Count( "text/html", s );
    int b = Count( "text/plain", s );
    int c = Count( "image/jpg", s );
    int d = Count( "image/png", s );
    std::cout &lt;&lt; a &lt;&lt; std::endl;
    std::cout &lt;&lt; b &lt;&lt; std::endl;
    std::cout &lt;&lt; c &lt;&lt; std::endl;
    std::cout &lt;&lt; d &lt;&lt; std::endl;
}
