SYNOPSIS

void * CSSMDLI DL_PassThrough
    (CSSM_DL_DB_HANDLE DLDBHandle,
    uint32 PassThroughId,
    const void * InputParams)

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.

PARAMETERS

DLDBHandle (input)

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.

PassThroughId (input)

An identifier assigned by a DL module to indicate the exported function to be performed.

InputParams (input)

A pointer to a module implementation-specific structure containing parameters to be interpreted in a function-specific manner by the requested DL module.

RETURN VALUE

A pointer to a module implementation-specific structure containing the output from the pass-through function. The output data must be interpreted by the calling application based on externally-available information. If the pointer is NULL, an error has occurred. Use CSSM_GetError to obtain the error code.
