NAME
RefreshFunctionTable - Gets EMM-defined API function (CDSA)
SYNOPSIS
# include <cssm.h>
CSSM_RETURN CSSMAPI RefreshFunctionTable
(CSSM_FUNC_NAME_ADDR_PTR FuncNameAddrPtr,
uint32 NumOfFuncNameAddr)
LIBRARY
Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)
PARAMETERS
FuncNameAddrPtr (input/output)
A pointer to a table mapping function names to EMM-defined
APIs.
NumOfFuncNameAddr (input)
The number of entries in the table referenced by
FuncNameAddrPtr.
DESCRIPTION
CSSM invokes this function to obtain the EMM-defined API function.
The table is returned to CSSM in FuncNameAddrPtr and CSSM returns
the table to the application. The application uses this table to
invoke the security services defined by the EMM's service category.
CSSM must obtain and forward the API table to the application on
behalf of the EMM because the application is not aware of the optional
nature of the EMM. Applications use CSSM to obtain the API function
table for basic module managers and elective module managers,
providing a uniform application programming model.
If the Elective Module Manager needs the service provider's SPI
function table in order to initialize the API function table, the
EMM can obtain the SPI function table by invoking the CSSM-provided
service cssm_GetAttachFunctions(). The service module may implement
only a subset of the defined functions and the EMM may wish to manage
these functions in a particular manner through the API mapping. The
elective module manager uses the SPI function table to dispatch
application calls for service to attached modules.
Multiple applications and multiple instances of a service module can
be concurrently active. The single elective module manager is
responsible for managing all of these concurrent sessions. After
completing initialization of the API function table, the EMM returns
the refreshed API table to CSSM.
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. See CDSA.
