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: |
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 |
