GFpECESInit_SM2

Initializes the ECES context.

Syntax

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.
