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
