The wsreg_set_data() function adds the key-value pair specified by key and value to the component specified by comp. If value is NULL, the key and current value is removed from the specified component.

The wsreg_get_data() function retrieves the value associated with the key specified by key from the component specified by comp.

The wsreg_get_data_pairs() function returns the list of key-value pairs from the component specified by comp.

The wsreg_set_data() function returns a non-zero value if the specified key-value pair was successfully added. It returns 0 if the addition failed. If NULL is passed as the value, the current key-value pair are removed from the specified component.

The wsreg_get_data() function returns the value associated with the specified key. It returns NULL if there is no value associated with the specified key. The char pointer that is returned is not a clone, so it must not be freed by the caller.

The wsreg_get_data_pairs() function returns a null-terminated array of char pointers that represents the specified component's list of data pairs. The even indexes of the resulting array represent the key names. The odd indexes of the array represent the values. If the specified component has no data pairs, NULL is returned. The resulting array (not its contents) must be released by the caller.

Any string data can be associated with a component. Because this information can be viewed in the prodreg registry viewer, it is a good place to store support contact information.

After the data pairs are added or removed, the component must be updated with a call to wsreg_register(3WSREG) for the modifications to be persistent.
