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

NAME

       wsreg_can_access_registry - determine access to product install registry

SYNOPSIS

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

       int wsreg_can_access_registry(int access_flag);

DESCRIPTION

       The wsreg_can_access_registry() function is used to determine what access, if any, an application has to the product install registry.

       The access_flag argument can be one of the following:

       O_RDONLY        Inquire about read only access to the registry.

       O_RDWR	       Inquire about modify (read and write) access to the registry.

RETURN VALUES

       The  wsreg_can_access_registry()  function  returns non-zero if the specified access level is permitted.  A return value of 0 indicates the
       specified access level is not permitted.

EXAMPLES

       Example 1: Initialize the registry and determine if access to the registry is permitted.

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

       int main(int argc, char **argv)
       {
	   int result;
	   if (wsreg_initialize(WSREG_INIT_NORMAL, NULL)) {
	       printf("conversion recommended, sufficient access denied
");
	   }

	   if (wsreg_can_access_registry(O_RDONLY)) {
	       printf("registry read access granted
");
	   } else {
	       printf("registry read access denied
");
	   }

	   if (wsreg_can_access_registry(O_RDWR)) {
	       printf("registry read/write access granted
");
	   } else {
	       printf("registry read/write access denied
");
	   }
       }

USAGE

       The wsreg_initialize(3WSREG) function must be called before calls to wsreg_can_access_registry() can be made.

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.
