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 isNULL.
- ippStsContextMatchErr
- Indicates an error condition if theIppsGFpECStatecontext parameter does not match the operation.
- ippStsBadArgErr
- Indicates an error condition ifnScalars<= 0 ornScalars> 6
