IppStatus ippsGFpECESInit_SM2(IppsGFpECState*
pEC
, IppsECES_StateSM2*
pState
, int
availableCtxSize
);
Include Files
ippcp.h
Parameters
pEC
Pointer to the elliptic curve context used in the ECES.
pState
Pointer to the buffer being initialized as the ECES context.
availableCtxSize
Available size of the buffer being initialized.
Description
The function initializes the memory buffer pointed to by
pState
as
IppsECES_StateSM2
.
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
IppsGFpECState
context parameter does not match the operation.
ippStsNotSupportedModeErr
Indicates an error condition if the
IppsGFpECState
context parameter defines an elliptic curve over an extension of the prime finite field.
ippStsSizeErr
Indicates an error condition if size of the initialized buffer is not big enough for the operation.
