* a URI handler where httpd_req_t* request pointer is valid
* - If output size is greater than input, then the value is truncated,
* accompanied by truncation error as return value
* - Use httpd_req_get_url_query_len() to know the right buffer length
* - Prior to calling this function, one can use httpd_req_get_url_query_len()
* to know the query string length beforehand and hence allocate the buffer
* of right size (usually query string length + 1 for null termination)
* for storing the query string
*
* @param[in] r The request being responded to
* @param[out] buf Pointer to the buffer into which the query string will be copied (if found)
