DL_PassThrough, CSSM_DL_PassThrough - Extend data storage module func‐
tionality (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
API: CSSM_RETURN CSSMAPI CSSM_DL_PassThrough (CSSM_DL_DB_HANDLE DLDB‐
Handle, uint32 PassThroughId, const void *InputParams, void **Output‐
Param) SPI: CSSM_RETURN CSSMDLI DL_PassThrough (CSSM_DL_DB_HANDLE DLDB‐
Handle, uint32 PassThroughId, const void *InputParams, void **Output‐
Param)
LIBRARY
Common Security Services Manager library (libcssm.so)
PARAMETERS
The handle pair that describes the add-in data storage library module
to be used to perform this function and the open data store upon which
the function is to be performed. An identifier assigned by a DL module
to indicate the exported function to be performed. A pointer to a mod‐
ule implementation-specific structure containing parameters to be
interpreted in a function-specific manner by the requested DL module.
A pointer to a module, implementation-specific structure containing the
output data. The service provider will allocate the memory for this
structure. The application should free the memory for the structure.
DESCRIPTION
This function allows applications to call data storage library module-
specific operations that have been exported. Such operations may
include queries or services that are specific to the domain represented
by a DL module.
RETURN VALUE
A CSSM_RETURN value indicating success or specifying a particular error
condition. The value CSSM_OK indicates success. All other values repre‐
sent an error condition.
ERRORS
Errors are described in the CDSA technical standard. See
