Usage of GFpECSignSM2

[Jim1990]

Hi, is there any sample for "GFpECSignSM2"? For below syntax which parameter is optional or not and which value should pass to them?

I'm a .NET developer and green hand in C language.

Now I have the SM2 private key file and I need to sign a message with SM2 algorithm.

Thanks!!!

IppStatus ippsGFpECSignSM2(const IppsBigNumState* 

pMsgDigest

, const IppsBigNumState* 

pRegPrivate

, const IppsBigNumState* 

pEphPrivate

, IppsBigNumState* 

pSignR

, IppsBigNumState* 

pSignS

, IppsGFpECState* 

pEC

, Ipp8u* 

pScratchBuffer

);
