Developer Reference for Intel® Integrated Performance Primitives Cryptography
Gets the size of the IppsECCPPoint context in bytes for a point on the elliptic curve point defined over GF(p).
IppStatus ippsECCPPointGetSize(int feBitSize, int* pSize);
ippcp.h
feBitSize |
Size (in bits) of the field element. |
pSize |
Pointer to the context size. |
The function computes the context size in bytes for a point on the elliptic curve defined over a prime finite field GF(p).
Context is a structure IppsECCPPoint intended for storing the information about a point on the elliptic curve defined over GF(p).
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. |
ippStsSizeErr |
Indicates an error condition if the value of the parameter feBitSize is less than 2. |
