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_compo‐
nent *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 component
specified by comp.
The wsreg_remove_child_component() function removes the component spec‐
ified 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 structure 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 lightweight
component references that can only be fully resolved using the registry
contents.
