GFpxGetSize

Gets the size of the context of a GF(p
d
) field.

Syntax

IppStatus ippsGFpxGetSize(const IppsGFpState*
pParentGF
, int
degree
, int*
pSize
);
Include Files
ippcp.h
Parameters
pParentGF
Pointer to the context of the finite field GF(
p
) being extended.
degree
Degree of the extension.
pSize
Pointer to the buffer size, in bytes, needed for the
IppsGFpState
context.
Description
The function returns the size of the buffer associated with the
IppsGFpState
context, suitable for storing data for the finite field GF(
p
d
) determined by the extension degree
d
supplied in the
degree
parameter.
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
.
ippStsContextMatchErr
Indicates an error condition if the
IppsGFpState
context parameter does not match the operation.
ippStsBadArgErr
Indicates an error condition if the degree of the extension is greater than or equal to 9 or is less than 2.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.
