CSSM_CL_HANDLE
The CSSM_CL_HANDLE is used to identify the association between an application thread and an instance of a CL module. CSSM_CL_HANDLE is assigned when an application causes OCSF to attach to a CL. It is freed when an application causes OCSF to detach from a CL. The application uses the CSSM_CL_HANDLE with every CL function call to identify the targeted CL. The CL module uses the CSSM_CL_HANDLE to identify the appropriate application's memory management routines when allocating memory on the application's behalf.
