PRNGSetModulus

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

Syntax

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

Parameters

pModulus	Pointer to the modulus value being set up.
pCtx	Pointer to the IppsPRNGState context.

Description

This function is declared in the ippcp.h file. 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.
