pDlyLine

Pointer to the tapsLen-length array holding the delay line values.

pDlyLineIndex

Pointer to the index of the delay line.

dlyLineIndex

Initial index of the delay line to be stored in the filter state structure pState.

Description

This function copies the delay line values from pDlyLine, and the current delay line index from dlyLineIndex, and stores them into the state structure pState.

Return Values
