get_req()

get_req() is the main function to get the parts of request.

#include "ecewo.h"

void hello_world(Req *req, Res *res)
{
    // It might be also &req->query or &req->headers
    const char *params = get_req(&req->params, "slug");
}

It’s much more easy to use get_params(), get_query() and get_headers macros instead.
