NAME

       wsreg_create_component, wsreg_free_component, wsreg_free_component_array - create or release a component

SYNOPSIS

       cc [flag ...]  file ...-lwsreg [library ...]
       #include <wsreg.h>

       Wsreg_component *wsreg_create_component(const char *uuid);

       void wsreg_free_component(Wsreg_component *comp);

       int wsreg_free_component_array(Wsreg_component **complist);

DESCRIPTION

       The wsreg_create_component() function allocates a new component and assigns the uuid (universal unique identifier) specified by uuid to the
       resulting component.

       The wsreg_free_component() function releases the memory associated with the component specified by comp.

       The wsreg_free_component_array() function frees the null-terminated array of component pointers specified by complist.  This  function  can
       be used to free the results of a call to wsreg_get_all(). See wsreg_get(3WSREG).

RETURN VALUES

       The wsreg_create_component() function returns a pointer to the newly allocated Wsreg_component structure.

       The  wsreg_free_component_array()  function returns a non-zero value if the specified Wsreg_component array was freed successfully.  Other-
       wise, 0 is returned.

USAGE

       A minimal registerable Wsreg_component configuration must include a version, unique name, display name, and an install location.

NAME

       wsreg_add_required_component, wsreg_remove_required_component, wsreg_get_required_components - add or remove a required component

SYNOPSIS

       cc [flag ...]  file ...-lwsreg [library ...]
       #include <wsreg.h>

       int wsreg_add_required_component(Wsreg_component *comp, const Wsreg_component *requiredComp);

       int wsreg_remove_required_component(Wsreg_component *comp, const Wsreg_component *requiredComp);

       Wsreg_component **wsreg_get_required_components(const Wsreg_component *comp);

DESCRIPTION

       The  wsreg_add_required_component()  function  adds the component specified by requiredComp to the list of required components contained in
       the component specified by comp.

       The wsreg_remove_required_component() function removes the component specified by requiredComp from the list of	required  components  con-
       tained in the component specified by comp.

       The wsreg_get_required_components() function returns the list of required components contained in the component specified by comp.

RETURN VALUES

       The wsreg_add_required_component() function returns a non-zero value if the specified required component was successfully added. Otherwise,
       0 is returned.

       The wsreg_remove_required_component() function returns a non-zero value if the specified required component was successfully removed.  Oth-
       erwise, 0 is returned.

       The wsreg_get_required_components() function returns a null-terminated array of Wsreg_component pointers that represents the specified com-
       ponent's list of required components.  If the specified component has no required 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  relationship  between two components in which one must be installed for the other to be complete is a dependent/required relationship.
       The component that is required by the other component is the required component.  The component that requires the other	is  the  dependent
       component.

       The  required  component must be installed and registered before the dependent component can be.  Uninstaller applications should check the
       registry before uninstalling and unregistering components so a successful uninstallation of one product will not result in another  product
       being compromised.

       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.
