Parameters

pState	Pointer to the FIR LMS filter state structure.
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

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsContextMatchErr	Indicates an error when the state identifier is incorrect.
