NAME
dat_provider_init - locate the Provider in the Static Registry SYNOPSIS
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> void dat_provider_init ( IN const DAT_PROVIDER_INFO *provider_info, IN const char * instance_data ) PARAMETERS
provider_info The information that was provided by the Consumer to locate the Provider in the Static Registry. instance_data The instance data string obtained from the entry found in the Static Registry for the Provider. DESCRIPTION
A constructor the Registry calls on a Provider before the first call to dat_ia_open(3DAT) for a given IA name when the Provider is auto- loaded. An application that explicitly loads a Provider on its own can choose to use dat_provider_init() just as the Registry would have done for an auto-loaded Provider. The Provider's implementation of this method must call dat_registry_add_provider(3DAT), using the IA name in the provider_info.ia_name field, to register itself with the Dynamic Registry. The implementation must not register other IA names at this time. Otherwise, the Provider is free to perform any initialization it finds useful within this method. This method is called before the first call to dat_ia_open() for a given IA name after one of the following has occurred: o The Provider library was loaded into memory. o The Registry called dat_provider_fini(3DAT) for that IA name. o The Provider called dat_registry_remove_provider(3DAT) for that IA name (but it is still the Provider indicated in the Static Registry). If this method fails, it should ensure that it does not leave its entry in the Dynamic Registry. RETURN VALUES
No values are returned. ATTRIBUTES

NAME
dat_pz_query - provides parameters of the Protection Zone SYNOPSIS
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> DAT_RETURN dat_pz_query ( IN DAT_PZ_HANDLE pz_handle, IN DAT_PZ_PARAM_MASK pz_param_mask, OUT DAT_PZ_PARAM *pz_param ) PARAMETERS
pz_handle: Handle for the created instance of the Protection Zone. pz_param_mask: Mask for Protection Zone parameters. pz_param: Pointer to a Consumer-allocated structure that the Provider fills with Protection Zone parameters. DESCRIPTION
The dat_pz_query() function provides the Consumer parameters of the Protection Zone. The Consumer passes in a pointer to the Consumer-allo- cated structures for Protection Zone parameters that the Provider fills. The pz_param_mask parameter allows Consumers to specify which parameters to query. The Provider returns values for pz_param_mask requested parameters. The Provider can return values for any other parameters. RETURN VALUES
DAT_SUCCESS The operation was successful. DAT_INVALID_PARAMETER The pz_param_mask parameter is invalid. DAT_INVALID_HANDLE The pz_handle parameter is invalid. ATTRIBUTES
