GFpGetElementOctString

Extracts an element of the finite field from the context to the output octet string.

Syntax

IppStatus ippsGFpGetElementOctString(const IppsGFpElement*
pA
, Ipp8u*
pStr
, int
strSize
, IppsGFpState*
pGFp
);
Include Files
ippcp.h
Parameters
pA
Pointer to the context of the finite field element.
pStr
Pointer to the octet string.
strSize
Size of the octet string buffer in bytes.
pGFp
Pointer to the context of the finite field.
Description
This function extracts the element of the finite field from the context to the octet string. If the string length is not enough to hold the whole finite field element, the function writes only a part of the element.
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 any of the
pGFp
and
pA
context parameters does not match the operation.
ippStsSizeErr
Indicates an error if the length of the string is zero or negative.
ippStsOutOfRangeErr
Indicates an error condition if the element
pA
does not belong to the finite field specified by the context
pGFp
.
