wsreg_set_instance(3WSREG)			    Product Install Registry Library Functions				wsreg_set_instance(3WSREG)

NAME

       wsreg_set_instance, wsreg_get_instance - set or get the instance of a component

SYNOPSIS

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

       int wsreg_set_instance(Wsreg_component *comp, int instance);

       int wsreg_get_instance(Wsreg_component *comp);

DESCRIPTION

       The  wsreg_set_instance()  function sets the instance number specified by instance of the component specified by comp.  The instance number
       and uuid are used to uniquely identify any component in the product install registry.

       The wsreg_get_instance() function determines the instance number associated with the component specified by comp.

RETURN VALUES

       The wsreg_set_instance() function returns a non-zero value if the instance was set correctly; otherwise 0 is returned.

       The wsreg_get_instance() function returns the instance number associated with the specified component.

EXAMPLES

       Example 1: Get the instance value of a registered component.

       The following example demonstrates how how to get the instance value of a registered component.

       #include <fcntl.h>
       #include <wsreg.h>

       int main (int argc, char **argv)
       {
	   char *uuid = "d6cf2869-1dd1-11b2-9fcb-080020b69971";
	   Wsreg_component *comp = NULL;

	   /* Initialize the registry */
	   wsreg_initialize(WSREG_INIT_NORMAL, NULL);
	   if (!wsreg_can_access_registry(O_RDWR)) {
	       printf("No permission to modify the registry.
");
	       return 1;
	   }

	   /* Create a component */
	   comp = wsreg_create_component(uuid);
	   wsreg_set_unique_name(comp, "wsreg_example_1");
	   wsreg_set_version(comp, "1.0");
	   wsreg_add_display_name(comp, "en", "Example 1 component");
	   wsreg_set_type(comp, WSREG_COMPONENT);
	   wsreg_set_location(comp, "/usr/local/example1_component");

	   /* Register */
	   wsreg_register(comp);

	   printf("Instance %d was assigned
", wsreg_get_instance(comp));

	   wsreg_free_component(comp);
	   return 0;
       }

USAGE

       Upon component registration with the wsreg_register(3WSREG) function, the instance number is set automatically.	The instance number  of  0
       (the  default) indicates to the wsreg_register() function that an instance number should be looked up and assigned during registration.	If
       a component with the same uuid and location is already registered in the product install registry, that component's instance number will be
       used during registration.

       After registration of a component, the wsreg_get_instance() function can be used to determine what instance value was assigned.

wsreg_set_parent(3WSREG)			    Product Install Registry Library Functions				  wsreg_set_parent(3WSREG)

NAME

       wsreg_set_parent, wsreg_get_parent - set or get the parent of a component

SYNOPSIS

       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);

DESCRIPTION

       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.

RETURN VALUES

       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_compo-
       nent(3WSREG).

USAGE

       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.
