NAME
       QuerySize,  CSSM_QuerySize, CSP_QuerySize - Get size of the output data
       (CDSA)

SYNOPSIS
       # include <cdsa/cssm.h>

       API:  CSSM_RETURN  CSSMAPI  CSSM_QuerySize  (CSSM_CC_HANDLE   CCHandle,
       CSSM_BOOL Encrypt, uint32 QuerySizeCount, CSSM_QUERY_SIZE_DATA_PTR Dat‐
       aBlockSizes) SPI: CSSM_RETURN CSSMCSPI  CSP_QuerySize  (CSSM_CSP_HANDLE
       CSPHandle,   CSSM_CC_HANDLE   CCHandle,	const  CSSM_CONTEXT  *Context,
       CSSM_BOOL Encrypt, uint32 QuerySizeCount, CSSM_QUERY_SIZE_DATA_PTR Dat‐
       aBlockSizes)

LIBRARY
       Common Security Services Manager library (libcssm.so)

API PARAMETERS
       The  handle  for an encryption and decryption context.  A boolean indi‐
       cating whether encryption is the operation for which  the  output  data
       size  should  be calculated. If CSSM_TRUE, the operation is encryption.
       If CSSM_FALSE the operation is decryption.  The number  of  entries  in
       the  array  of  DataBlockSizes.	An array of data block input sizes and
       corresponding entries for the data block output sizes that are returned
       by this function.

SPI PARAMETERS
       The  handle  that  describes  the add-in cryptographic service provider
       module used to perform calls to CSSM for the memory  functions  managed
       by   CSSM.   Pointer  to	 CSSM_CONTEXT  structure  that	describes  the
       attributes with this context.

DESCRIPTION
       This function queries for the size of the output	 data  for  a  crypto‐
       graphic	operation.  If the context is an encryption or decryption con‐
       text type then the Encrypt parameter will determine which operation  is
       being  performed.  If Encrypt is set to CSSM_TRUE then it is an encrypt
       operation, otherwise it is a decrypt operation. For all	other  context
       types  the Encrypt parameter is ignored. This function can also be used
       to query the output size requirements for the intermediate steps	 of  a
       staged  cryptographic  operation.  There	 may be algorithm-specific and
       token-specific rules restricting the lengths  of	 data  following  data
       update calls.

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
       CDSA_intro(3).  CSSMERR_CSP_QUERY_SIZE_UNKNOWN
