PRNGSetModulus

Sets the initial state with the given input modulus for the pseudorandom number generation.

Syntax

IppStatus ippsPRNGSetModulus(const IppsBigNumState* pMod, IppsPRNGState* pCtx);

Include Files

ippcp.h

Parameters

pMod

Pointer to the modulus value being set up.

pCtx

Pointer to the IppsPRNGState context.

Description

The function resets the modulus value with the supplied value up to 160 bit length. The supplied big number should be created prior to the function call using the appropriate Big Number Arithmetic functions (see Example “Create a Big Number”).

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.

ippStsBadArgErr

Indicates an error condition if the size of pMod is not 160 bit.
