Parameters
- pSgn
- Pointer to the sign ofIppsBigNumState*x.
- bitSize
- Length of the integer big number in bits.
- ppData
- Double pointer to the data array.
- pBN
- Integer big number of the contextIppsBigNumState.
Description
The function extracts from the input structure the main characteristics of the integer big number: sign, length, and pointer to the data array. You can extract either the entire set or any subset of these characteristics. To turn off extraction of a particular characteristic, set the appropriate function parameter to NULL.
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 the context parameter does not match the operation.
