MontInit
Initializes the context and partitions the specified buffer space.
Syntax
IppStatus ippsMontInit(IppsExpMethod method, int length, IppsMontState *pCtx);
Include Files
ippcp.h
Parameters
| method | Selected exponential method. | 
| length | Data field length for the modulus in Ipp32u chunks. | 
| pCtx | Pointer to the context IppsMontState. | 
Description
The function initializes the *pCtx buffer as the IppsMontState context. The function then partitions the buffer using the selected modular exponential method in such a way as to carry up to length*sizeof(Ipp32u)-bit big number modulus and execute various Montgomery modulus operations.
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. | 
| ippStsLengthErr | Indicates an error condition if length is less than or equal to 0 or greater than 512. |
