- set or get the parent of a component
cc [flag …] file …-lwsreg [library …] #include <wsreg.h> void wsreg_set_parent(Wsreg_component *comp, const Wsreg_component *parent);
Wsreg_component *wsreg_get_parent(const Wsreg_component *comp);
The wsreg_set_parent() function sets the parent specified by parent of the component specified by comp.
The wsreg_get_parent() function gets the parent of the component specified by comp.
The wsreg_get_parent() function returns a pointer to a Wsreg_component structure that represents the parent of the specified component. If the specified component does not have a parent, NULL is returned. If a non-null value is returned, it the caller's responsibility to release the memory associated with the resulting Wsreg_component pointer with a call to wsreg_free_component(). See wsreg_create_component(3WSREG).
The parent of a component is set as a result of registering the parent component. When a component that has children is registered, all of the child components are updated to reflect the newly registered component as their parent. This update only occurs if the child component does not already have a parent component set.
The specified parent component is reduced to a lightweight component reference that uniquely identifies the parent in the product install registry. This lightweight reference includes the parent's uuid and instance number.
The parent must be registered before a call to wsreg_set_parent() can be made, since the parent's instance number must be known at the time the wsreg_set_parent() function is called.
A process needing to call wsreg_set_parent() or wsreg_get_parent() must have read access to the product install registry.
