Parameters

pState

Pointer to the IIRIIR filter state structure.

pDlyLine

Pointer to the array containing the delay line values. The number of elements in the array is order.

Description

This function copies the delay line values from the corresponding pState structure and stores them into the pDlyLine array.

The corresponding filter state structure must be initialized beforehand by the initialization function.

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.
