The wsreg_get() function queries the product install registry for a component that matches the query specified by query.

The wsreg_get_all() function returns all components currently registered in the product install registry.

The wsreg_get() function returns a pointer to a Wsreg_component structure representing the registered component. If no component matching the specified query is currently registered, wsreg_get() returns NULL.

The wsreg_get_all() function returns a null-terminated array of Wsreg_component pointers. Each element in the resulting array represents one registered component.

The wsreg library must be initialized by a call to wsreg_initialize(3WSREG) before any call to wsreg_get() or wsreg_get_all().

The Wsreg_component pointer returned from wsreg_get() should be released through a call to wsreg_free_component(). See wsreg_create_component(3WSREG).

The Wsreg_component pointer array returned from wsreg_get_all() should be released through a call to wsreg_free_component_array(). See wsreg_create_component(3WSREG).
