User’s Implementation of a Pseudorandom Number Generator
Both functions ippsPRNGGen and ippsPRNGGen_BN, as well as their supplementary functions represent the implementation of the pseudorandom number generator in the IPPCP library. This given implementation is based on recommendations made in FIPS PUB 186-2. If you prefer to use the implementation of the pseudorandom number generator which is different from the given, you can still use IPPCP library. To do this, use the following definition of the generator introduced by the IPPCP library:
Syntax
typedef IppStatus(_STDCALL *IppBitSupplier)(Ipp32u* pData, int nBits, void* pEbsParams);
Parameters
pData |
Pointer to the output data. |
nBits |
Number of generated data bits. |
pEbsParams |
Pointer to the user defined context. |
Description
This declaration is included in the ippcp.h file. The function generates any data (probably pseudorandom numbers) of the specified nBits length.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsErr |
Indicates an error condition. |
