Libraries: ippcore.lib, ippvm.lib

Parameters

pState

Pointer to the IIR filter state structure.

pDlyLine

Pointer to the array holding the delay line values. The number of elements in the array is order for arbitrary filters and 2*numBq for BQ filters. If the pointer is NULL, then the delay line values in the state structure are initialized to zero.

Description

This function copies the delay line values from pDlyLine and stores them into the state structure pState. If the pointer is NULL, then the delay line values in the state structure are initialized to zero.

The filter state must be initialized beforehand by one of the initialization functions.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when the pState pointer is NULL.

ippStsContextMatchErr

Indicates an error when the state identifier is incorrect.
