GFpGetSize
Gets the size of the context of a GF(q) field.
Syntax
IppStatus ippsGFpGetSize(int febitSize, int* pSize);
Include Files
ippcp.h
Parameters
febitSize |
Size, in bytes, of the odd prime number q (modulus of GF(q)). |
pSize |
Pointer to the buffer size, in bytes, needed for the IppsGFpState context. |
Description
This function returns the size of the buffer associated with the IppsGFpState context, which you can use to store data of the finite field GF(q) determined by the odd prime number q of size not greater than febitSize bit.
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. |
ippStsSizeErr |
Indicates an error condition if febitSize is less than 2 or greater than 1024. |
