GFpECKeyExchangeSM2_GetSize#
Gets the size of the SM2 Key Exchange Elliptic Curve context.
Syntax#
IppStatus ippsGFpECKeyExchangeSM2_GetSize(const IppsGFpECState* pEC, int* pSize)
Include Files#
ippcp.h
Parameters#
pEC |
Pointer to the elliptic curve context. |
pSize |
Pointer to the size, in bytes, of the IppsGFpECKeyExchangeSM2State context. |
Description#
The function computes the size of the buffer, in bytes, for the IppsGFpECKeyExchangeSM2State context to be used later.
The pEC parameter represents a properly initialized elliptic curve using the SM2 Key Exchange scheme.
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 are NULL. |
ippStsContextMatchErr |
Indicates an error condition if the |
