GFpxGetSize¶
Gets the size of the context of a GF(pd) 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( |
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(pd) 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. |
