{

char *request = getenv("REQUEST_METHOD");

if( NULL == request )
{

}

if (request == "GET")
{
if (getenv("QUERY_STRING") != 0)
{
query = getenv("QUERY_STRING");
}
else
{
query == "error";
}
}

int start;
int end;

if (query == "error" )
{
return ("error");
}

else
{
start = query.find(formname);
if (query.find(formname) !=string::npos )
{
return "error";
}

start += 1;

if (query.find("&", start) !=string::npos )

{
end = query.rfind(formname, end);
}
else
{
end = query.find("&", start);
end -= 1;
}

char *tmp;
query.substr(start,end);
query.copy(tmp,string::npos);
return tmp;

}
