GFpSetElementOctString¶

Assigns a value from the input octet string to an element of the finite field.

Syntax¶

IppStatus ippsGFpSetElementOctString(const Ipp8u* pStr, int strSize, IppsGFpElement* pR, IppsGFpState* pGFp);

ippcp.h

pStr	Pointer to the octet string.
strSize	Size of the octet string buffer in bytes.
pR	Pointer to the context of the finite field element.
pGFp	Pointer to the context of the finite field.

This function assigns a value from the input octet string to an element of the finite field.

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition in any of the following cases: Either pR or pGFp is NULL. The length of the string is greater than zero and the pointer pStr is NULL.
ippStsContextMatchErr	Indicates an error condition if any of the pGFp and pR context parameters does not match the operation.
ippStsSizeErr	Indicates an error condition in any of the following cases: strSize exceeds the length of an element of the finite field. strSize ≤ 0. The maximum length of the element stored in the context pR exceeds the maximum length of an element of the finite field specified by the context pGFp.
ippStsOutOfRangeErr	Indicates an error condition in any of the following cases: The length of the element stored in the context pR is not equal to the length of an element of the finite field specified by the context pGFp. The value defined by pStr exceeds the modulus q of the basic prime finite field.
