NAME
   DecryptDataInit,
   CSSM_DecryptDataInit,
   CSP_DecryptDataInit  - Initialize the staged decrypt function(CDSA)

 SYNOPSIS
   # include <cssm.h>

    API:
        CSSM_RETURN CSSMAPI CSSM_DecryptDataInit
        (CSSM_CC_HANDLE CCHandle)
    SPI:
        CSSM_RETURN CSSMCSPI CSSM_CSP_DecryptDataInit
        (CSSM_CSP_HANDLE CSPHandle,
        CSSM_CC_HANDLE CCHandle,
        const CSSM_CONTEXT *Context,
        CSSM_PRIVILEGE Privilege)

 LIBRARY
   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 API PARAMETERS
   CCHandle (input)
           The handle that describes the context of this cryptographic
           operation used to link to the CSP-managed information.

 SPI PARAMETERS
   CSPHandle (input)
           The handle that describes the add-in cryptographic service
           provider module used to perform calls to CSSM for the memory
           functions managed by CSSM.

   Context (input)
           Pointer to CSSM_CONTEXT structure that describes the
           attributes with this context.

   Privilege (input)
           The export privilege to be applied during the cryptographic
           operation. This parameter is forwarded to the CSP after CSSM
           verifies the caller and service provider privilege set includes
           the specified PRIVILEGE.

 DESCRIPTION
   This function initializes the staged decrypt function.

   The CSP can require that the cryptographic context include access
   credentials for authentication and authorization checks when using a
   private key or a secret key.

 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.

   None specific to this call.
