HashStateMethodSet

Updates the IppsHashState_rmf structure with a new pointer to IppsHashMethod and initializes it with the pre-defined hash algorithm parameters.

Parameters

pState

Pointer to the IppsHashState_rmf context being updated.

pMethod

Pointer to the method for the update of the context.

Description

Each of these functions:

  • Accepts pointer to IppsHashState_rmf context, which is proceeded with ippsHashInit function before.

  • Updates stored inside of the context pointer to IppsHashMethod.

  • Initializes it to the method-defined implementation of a particular hash algorithm.

Use these functions in calls to HashInit and HashMessage.

Return Values

ippStsNoErr

Indicates no errors. Any other value indicates an error or warning.

ippStsNullPtrErr

Indicates an error condition if any of the specified pointers are NULL.
