Gets the size of the IppsECCBPoint context in bytes for a point on the elliptic curve point defined over GF( 2m).
IppStatus ippsECCBPointGetSize(int feBitSize, int* pSize);
feBitSize |
Size (in bits) of the field element. |
pSize |
Pointer to the context size. |
This function is declared in the ippcp.h file.
The function computes the context size in bytes for a point on the elliptic curve defined over a binary finite field GF(2m).
Context is a structure IppsECCBPoint intended for storing the information about a point on the elliptic curve defined over GF(2m).
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 1. |
