GFpECScratchBufferSize

GFpECScratchBufferSize#

Gets the size of the scratch buffer.

Syntax#

IppStatus ippsGFpECScratchBufferSize(int nScalars, const IppsGFpECState* pEC, int* pBufferSize);

Include Files#

ippcp.h

Parameters#

nScalars
Number of scalar values. This may take the following values:

  • Number of scalar values used in the multiplication operation.

  • 1 if it is not applicable.

pEC

Pointer to the context of the elliptic curve.

pBufferSize

Pointer to the calculated buffer size in bytes.

Description#

This function computes the size of the scratch buffer for functions that require an external scratch buffer.

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.

ippStsBadArgErr

Indicates an error condition if nScalars <= 0 or nScalars > 6
