CSSM_SPI_ModuleLoad

NAME

CSSM_SPI_ModuleLoad — Initialize process between CSSM and the add-in service module (CDSA)

SYNOPSIS

# include <cssm.h>

CSSM_RETURN CSSMSPI CSSM_SPI_ModuleLoad
(const CSSM_GUID *CssmGuid,
const CSSM_GUID *ModuleGuid,
CSSM_SPI_ModuleEventHandler CssmNotifyCallback,
void* CssmNotifyCallbackCtx)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

`CssmGuid` (`input`)		The CSSM_GUID of the caller. Used to locate the caller's signed manifest credentials.
`ModuleGuid` (`input`)
		The CSSM_GUID of the invoked service provider module. Used to locate the module's signed manifest credentials.
`CssmNotifyCallback` (`input`)
		A function pointer for the CSSM event handler that manages events of type CSSM_MODULE_EVENT.
`CssmNotifyCallbackCtx` (`input`)
		The context to be returned to CSSM as input on each callback to the event handler defined by `CssmNotifyCallback`.

DESCRIPTION

This function completes the module initialization process between CSSM and the add-in service module. Before invoking this function, CSSM verifies the add-in service module's manifest credentials. If the credentials verify this module is loaded (physically if required), the CSSM_SPI_ModuleLoad() function is invoked.

The CssmGuid parameter identifies the caller and should be used by the module to locate the caller's signed manifest credentials and to complete integrity verification and secure linkage checks on the caller. The ModuleGuid identifies the invoked module and should be used by the module to locate its credentials and to complete an integrity self-check.

The CssmNotifyCallback and CssmNotifyCallbackCtx parameters define a callback and callback context respectively. The module must retain this information for later use. The module should use the callback to notify CSSM of module events of type CSSM_MODULE_EVENT in any ongoing, attached sessions.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.
