wsreg_set_data(3WSREG) Product Install Registry Library Functions wsreg_set_data(3WSREG) NAME
wsreg_set_data, wsreg_get_data, wsreg_get_data_pairs - add or retrieve a key-value pair SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_set_data(Wsreg_component *comp, const char *key, const char *value); char *wsreg_get_data(const Wsreg_component *comp, const char *key); char *wsreg_get_data_pairs(const Wsreg_component *comp); DESCRIPTION
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. RETURN VALUES
The wsreg_set_data() function returns a non-zero value if the specified key-value pair was successfully added. It returns 0 if the addi- tion 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 speci- fied component has no data pairs, NULL is returned. The resulting array (not its contents) must be released by the caller. USAGE
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. ATTRIBUTES

wsreg_add_child_component(3WSREG) Product Install Registry Library Functions wsreg_add_child_component(3WSREG) NAME
wsreg_add_child_component, wsreg_remove_child_component, wsreg_get_child_components - add or remove a child component SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_add_child_component(Wsreg_component *comp, const Wsreg_component *childComp); int wsreg_remove_child_component(Wsreg_component *comp, const Wsreg_component *childComp); Wsreg_component **wsreg_get_child_components(const Wsreg_component *comp); DESCRIPTION
The wsreg_add_child_component() function adds the component specified by childComp to the list of child components contained in the compo- nent specified by comp. The wsreg_remove_child_component() function removes the component specified by childComp from the list of child components contained in the component specified by comp. The wsreg_get_child_components() function returns the list of child components contained in the component specified by comp. RETURN VALUES
The wsreg_add_child_component() function returns a non-zero value if the specified child component was successfully added; otherwise, 0 is returned. The wsreg_remove_child_component() function returns a non-zero value if the specified child component was successfully removed; otherwise, 0 is returned. The wsreg_get_child_components() function returns a null-terminated array of Wsreg_component pointers that represents the specified compo- nent's list of child components. If the specified component has no child components, NULL is returned. The resulting array must be released by the caller through a call to wsreg_free_component_array(). See wsreg_create_component(3WSREG). USAGE
The parent-child relationship between components in the product install registry is used to record a product's structure. Product struc- ture is the arrangement of features and components that make up a product. The structure of installed products can be displayed with the prodreg GUI. The child component must be installed and registered before the parent component can be. The registration of a parent component that has child components results in each of the child components being updated to reflect their parent component. Read access to the product install registry is required in order to use these functions because these relationships are held with light- weight component references that can only be fully resolved using the registry contents.
