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_reg‐
istry_add_provider(3DAT), using the IA name in the
provider_info.ia_name field, to register itself with the Dynamic Reg‐
istry. 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.
