+ * @brief Assigns the default value to a configuration parameter if available.
+ *
+ * This function checks the type of the parameter and assigns its default value
+ * if it is defined. It handles various parameter types, including strings, integers,
+ * arrays, doubles, IPv4 addresses, and lists. If the parameter is marked with
+ * PARAMFLAG_DONOTREAD, it is ignored.
+ *
+ * @param[in]  cfg       Pointer to the configuration module interface.
+ * @param[in]  cfgoption Pointer to the parameter definition structure.
+ * @param[in]  prefix    Optional prefix for the parameter name (can be NULL).
+ * @return 1 if the default value was set, 0 if ignored, or -1 on error/unsupported type.
