Include Files
ippcp.h
Parameters
pMD |
Pointer to the MAC value. |
mdLen |
Specified length of the MAC. |
pState |
Pointer to the IppsAES_CMACState context. |
Description
The function completes calculation of the MAC of a message, stores the result in the memory at the address of pMD, and prepares the context for computation of the MAC of another message.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsLengthErr |
Indicates an error condition if mdLen is less than 1 or greater than cipher’s data block length. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
