GFpScratchBufferSize¶
Gets the size of the scratch buffer.
Syntax¶
IppStatus ippsGFpScratchBufferSize(int nExponents, int ExpBitSize, const IppsGFpState* pGFp, int* pBufferSize);
Include Files¶
ippcp.h
Parameters¶
nExponents |
Number of exponents. |
ExpBitSize |
Maximum bit size of the exponents. |
pGFp |
Pointer to the context of the finite field. |
pBufferSize |
Pointer to the calculated buffer size in bytes. |
Description¶
This function computes the size of the scratch buffer for the ippsGFpExp and ippsGFpMultiExp functions. The pGFp parameter specifies the context of the finite field.
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 pGFp context parameter does not match the operation. |
ippStsBadArgErr |
Indicates an error condition in the following cases:
