Common Data Security Architecture (CDSA) White Paper

Certificate Library Services (CL) API

Extensibility Functions

CL_PassThrough ( )

Performs a function indicated by an operation ID, which identifies an operation exported by CL for use by an application or other module. These operations are specific to the data format of the certificates and CRLs manipulated by the CL module.

The HPUX bundled CL supports the following pass-through functions. Each pass-through ID defined in cdsa/x509defs.h represents a pass-through function available to applications. To perform the function, applications invoke the CL API CSSM_CL_PassThrough(), which has the following syntax:

output = CSSM_CL_PassThrough(CLHandle, PassThroughID, Input);

•CLHandle is the handle returned by CSSM_ModuleAttach() when attaching the CL.

•PassThroughID is a pass-through number to indicate the function to be performed.

•Input is the input parameter required to perform the specific function. Each pass-through ID has a specific input requirement.

•Output is the result returned by the function.

The information that follows specifies the function performed, input requirement and output for each pass-through ID. For further details about the data structures, see the CSSM(4) manpage:
