VerifyDataUpdate(3)VerifyDataUpdate(3)NAME
VerifyDataUpdate, CSSM_VerifyDataUpdate, CSP_VerifyDataUpdate - Con‐
tinue the staged verification (CDSA)
SYNOPSIS
# include <cdsa/cssm.h>
API: CSSM_RETURN CSSMAPI CSSM_VerifyDataUpdate (CSSM_CC_HANDLE CCHan‐
dle, const CSSM_DATA *DataBufs, uint32 DataBufCount) SPI: CSSM_RETURN
CSSMCSPI CSP_VerifyDataUpdate (CSSM_CSP_HANDLE CSPHandle, CSSM_CC_HAN‐
DLE CCHandle, const CSSM_DATA *DataBufs, uint32 DataBufCount)
LIBRARY
Common Security Services Manager library (libcssm.so)
API PARAMETERS
The handle that describes the context of this cryptographic operation
used to link to the CSP-managed information. A pointer to a vector of
CSSM_DATA structures that contain the data to be operated on. The num‐
ber of DataBufs to be verified.
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.
DESCRIPTION
This function continues the staged verification process over all data
contained in the set of input. Verification will be based on the signa‐
ture presented as input when finalizing the staged verification
process.
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).
None specific to this call.
