PRNGGetSeed
Extracts the seed value of the pseudorandom number generator from the context structure.
Syntax
IppStatus ippsPRNGGetSeed(const IppsPRNGState* pCtx, IppsBigNumState* pSeed);
Include Files
ippcp.h
Parameters
| pCtx | Pointer to the IppsPRNGState context. | 
| pSeed | Pointer to the seed value. | 
Description
The function extracts the seed value of the pseudorandom number generator from the IppsPRNGState context structure into 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 *pSeed is not a IppsBigNumState structure or *pCtx is not a IppsPRNGState structure. | 
| ippOutOfRangeErr | Indicates an error condition if the length of the actual seed exceeds *pSeed. |
