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
