GFpECESInit_SM2¶
Initializes the ECES context.
Syntax¶
IppStatus ippsGFpECESInit_SM2(IppsGFpECState* pEC, IppsECES_StateSM2* pState, int availableCtxSize);
Include Files¶
ippcp.h
Parameters¶
pEC |
Pointer to the elliptic curve context used in the ECES. |
pState |
Pointer to the buffer being initialized as the ECES context. |
availableCtxSize |
Available size of the buffer being initialized. |
Description¶
The function initializes the memory buffer pointed to by pState as IppsECES_StateSM2.
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. |
ippStsContextMatchErr |
Indicates an error condition if the IppsGFpECState context parameter does not match the operation. |
ippStsNotSupportedModeErr |
Indicates an error condition if the IppsGFpECState context parameter defines an elliptic curve over an extension of the prime finite field. |
ippStsSizeErr |
Indicates an error condition if size of the initialized buffer is not big enough for the operation. |
