);

Parameters
- febitSize
- Size, in bytes, of the odd prime numberq(modulus of GF(q)).
- pSize
- Pointer to the buffer size, in bytes, needed for theIppsGFpStatecontext.
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 isNULL.
- ippStsSizeErr
- Indicates an error condition iffebitSizeis less than 2 or greater than 1024.
