PRNGSetSeed

Sets up the seed value for the pseudorandom number generator.

Syntax

IppStatus ippsPRNGSetSeed(const IppsBigNumState* pS
eed
, IppsPRNGState*
pCtx
);
Include Files
ippcp.h
Parameters
pSeed
Pointer to the seed value being set up.
pCtx
Pointer to the
IppsPRNGState
context.
Description
The function resets the seed value with the supplied value of
seedBits
bit length. The supplied big number should be created prior to the function call using the appropriate Big Number Arithmetic functions (see Example ).
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 context parameter does not match the operation.
This function restarts the pseudorandom number generation process, which results in losing already generated pseudorandom numbers.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
